 [3]   25
 [4]   30

3.The ratio of weekly incomes of A and B is  9:7 and the ratio of their expenditures is 4:3. If each saves Rs.200/- per week, then the sum of their weekly incomes is:
[1]Rs.3200/-
[2]Rs.4,200/-
[3]Rs.4,800/-
[4]Rs.56,00/-

4.Aman is noticed by a Sumen from a distance of 200 m. The Amen starts running and the Sumen chases him. The Amen and the Sumen at the rate of 10 km and 11 km per hour respectively. What is the distance between them after 6 minutes?

5.If 30% of A is added to 40% of B, the answer is 80% of B.What percentage of A is B?
[1] 30%
[2]40%
[3]70%
[4]75%




Answer
1.[4]Let the number x be subtracted then,
17 - x = 1
 24- x    2
=>34 - 2x = 24 - x  => x = 10

2[2].Average = (10+15+20+25+30)=100=20 
                          5                          5

3.[1]et the weekly income of Aand B respective be Rs.9x and Rs.7x and their expenditure be Rs.4y and Rs.3y
According to question
9x - 4y = Rs.200/------(1)
7x - 3y = Rs.200/------(2)
By solving of eq.(1) and (2)
x = Rs.200/-     u = Rs.400/-
So,sum of their weekly incomes = 9x +7x = 16x
= 16* 200 = Rs.3,200

4.[1]Relative speed of the Amen and Sumen  =  (11 – 10) km/hr = 1 km/hr

Distance covered in 6 minutes  = {(1/60 * 6)} km   = {1/10} km = 100 m

Distance between the Amen and Sumen = (200 – 100) m = 100 m. 


5.[4] A * 30 + B * 40 = B * 80
             100       100         100
      => A * 30 = B * 80 - B * 40
               100          100       100

     =>A * 30 = B * 40       
              100        100
    =>3A = 4B
Required percent = 3/4 * 100 = 75%

[5] None of these.


Answer1.[2]Let the man's age be 31x years and that of his son be 13x years.
According to the question,
31x  + 13x  = 2*44

=>44x = 88 => 88/44 = 2
Son's age = 13x
= 13*2 = 26 years

2.[2]Speed[1] = 50 miles/hour    Time[1]= 2 1/2  hour = 5/2 hour
 =>Distance1 = Speed1 × Time1 = 50×5/2=25×5=125 miles
Speed[2] = 70 miles/hour    Time[2] = 1 1/2 hour = 3/2 hour
Distance[2] = Speed2 × Time2 = 70×3/2=35×3=105 miles
Total Distance = Distance1 + Distance2 =125+105=230 miles

3.[1]SI= P*R*T
              100

                       100
      = Rs. 45309.6     
4[2].Let the speed of the stream be x km/hr. Then,

Speed downstream = (15 + x) km/hr,

Speed upstream = (15 - x) km/hr.

   
  30       +             30         =  4 1/2
(15 + x)        (15 - x)

900             =   9
225 - x2           2

9x2 = 225

x2 = 25

x = 5 km/hr.        

5[1]50 *50 = 2500
51 *51 = 2600
Least  number to be added
= 2601 - 2600  =1

[1]15.5   
[2]16.15
[3]10 .   
[4]None of these

Answer
1.[1]Let speed of first train = x km/h
        Let speed of second train = y km/h
According to question
120 + 600-129  =  8   .............................(1)
  x           y
200 600-200  = 25  ............................(2)
 x             y               3

solving (1) and (2) we get
x = 60,  y = 80
Required ratio = 60: 80 = 3 :4

2.[3]Remaining distance = 3 km
Remaining time =1 * 45 = 15 min = 0.025 h
                           3
 Required speed =     = 12 km/h
                           0.025
3.[2]: The area of a square is represented by the formula, A=s2.
 Substituting 16 for A gives: 16=s2.
Solving for s shows each side length to be 4 feet.
 Thus, the perimeter is equal to the product of 4 and 4 ft, or 16 ft.

4.[4]
Let his add money = Rs x
According to questipn
(4800 + x ) *12 * 3  - 4800 * 9* 3 = 720
   100                               100
=> 48*36 + x * 36 -  48 *27 = 270
                        100
=>x = 288*100 = Rs 800/-
                    36
5.[1]Total investment = Rs. (7200+200+ 600) Rs. 8000.
Total receipt Rs. (330 x 28) = Rs. 9240.
profit % = [1240/8000] * 100 = 15.5

Answer
1[3]
the no. of persons who like Mirinda only
= 510 - (180 + 90 + 72) = 168

2.[5]Req.difference = 240 +144+ 180 + 90 - 540 = 654 - 540 = 114

3.[3] Total no. of persons who like more than  one drink.= 180 +144+72 +90 = 486
Req percentage = 486/1440 * 100 = 33.75%

4.[2] Required no. of students - 55-(23+12+125) = 55 - 50 = 5

5.[3]Let x be the no. of students who drink both
 650 - x  + x + 390 - x + 30 = 1000
or -x = 1000 - 1070 or x = 70

A.     2.91 m  
B.     3 m
C.     5.82
D.        4
E     None of these





Answer:and Explanation:
1. E
Time taken by train to cross a man =     Length of train        =>   Speed =     L          (i)
                                                            Speed of train                            9

Time taken by train
to cross a platform =     (Length of train +Length of platform)
                                                    Speed of train             =>   Speed =    L    + 240     ....(ii)   
                                                                                                                    24
From (i) and (ii), we get     L=     L + 240     .
                                         9         24

Thus, L can be obtained. So both I and II are necessary to get the answer.

.
2.[D].

3.[B]
.Let be the original number of men be x
 60x = (x + 8) 50
 60x = 50x + 400 
10 x = 400 
x = 40

4.B
Let 'd' be the distance between the stations X and Y.

Time taken by the passenger train to cover the distance 'd' = d/60 hour
Time taken by the goods train to cover the distance 'd' = d/20 hour
Time difference between these two trains is given by 50 minutes or 50/60 hour

i.e., (d/20) - (d/60) = 50/60
      =>(3d - 1d)/60 = 50/60

        =>   2d / 60 = 50/60

    =>d = 256


5.B
Area of the park = (60 x 40) m2 = 2400 m2.

Area of the lawn = 2109 m2.

Area of the crossroads = (2400 - 2109) m2 = 291 m2.

Let the width of the road be x metres. Then,

60x + 40x - x2 = 291

x2 - 100x + 291 = 0

(x - 97)(x - 3) = 0

x = 3.

Here you will see that radius of the circle is equal to the diameter of the innermost square that is

Ï€r2=77
             
r=3.5√2
              
2r=7√2

Then the diagonal of the square is 14 sq units.

Which means the diagonal of the fifth sqaure would be 14+12 units = 26.
                                                                                         
Which means the side of the fifth square would be 26√2

Therefore, the area of the fifth sqaure = 1352 sq units.

Area of the first square = 98 sq units.

Hence, the difference would be 1254 sq units.

A. 10%
B. 12.5%
C. 8%
D. 12%

5.P can lay railway track between two stations in 16 days. Q can do the same job in 12 days. With the help of R, they completes the job in 4 days. How much days does it take for R alone to complete the work?
A. 9(3/5) days
B. 9(1/5) days
C. 9(2/5) days
 D. 10 days

Answer
1.b
S.I. on Rs. 1600 = T.D. on Rs. 1680.

Rs. 1600 is the P.W. of Rs. 1680, i.e., Rs. 80 is on Rs. 1600 at 15%.

Time =  100 x 80     year     =     1     year = 4 months.
           1600 x 15                       3
2.B
Area of the wet surface =
2[lb+bh+hl] - lb = 2 [bh+hl] + lb
= 2[(4*1.25+6*1.25)]+6*4 = 49 m square 

3.CPrincipal (P) = $ 5400,
Amount (A) = $ 6000
Simple Interest (SI) = Amount (A) – Principal (P)
= 6000 - 5400
= 600
Therefore, Richard got an interest of $ 600

4c
,Let the price of 1 litre of gasoline be $x and let Ron initially buy 'y' litres of gasoline.

Therefore, he would have spent $xy on gasoline.

When the price of gasoline increases by 25%, the new price per litre of gasoline is 1.25x.

Ron intends to increase the amount he spends on gasoline by 15%.

i.e., he is willing to spend xy + 15% of xy = 1.15xy

Let the new quantity of gasoline that he can get be 'q'.

Then, 1.25x * q =
1.15xy/1.25x  =  1.15/1.25 y = 0.92y.

As the new quantity that he can buy is 0.92y, he gets 0.08y lesser than what he used to get earlier.

Or a reduction of 8%.

5.a
Amount of work P can do in 1 day = 1/16

Amount of work Q can do in 1 day = 1/12

Amount of work P, Q and R can together do in 1 day = 1/4

Amount of work R can do in 1 day = 1/4 - (1/16 + 1/12) = 3/16 – 1/12 = 5/48

=> Hence R can do the job on 48/5 days = 9 (3/5) days

B.     299
C.     322   
D.     345
E.      364

 Answer
 1.[d]
The easiest way to solve these kinds of problems is to assume a cost price for the merchant.

To make calculations easy, let us assume that the cost price = $100

The merchant marks his goods up by 50%.

Therefore, his quoted price = cost price + mark up

= $100 + 50% of $100 = 100 + 50 = $150

Now, the merchant offers a discount of 20% on his quoted price

Therefore, amount of discount = 20% of $150 = 20% of 150 = $30

Therefore, he finally sells it for $150 - $30 = $ 120.

We assumed his cost to be $ 100 and he sold it finally for $ 120.

Therefore, his net profit = $ 20 on his cost of $ 100

Hence, his % profit = = 20%.


2.[B] The cost price of 11 pencils = S.P of 10 pencils
Let C.P of 1 pencil is $1 .
C.P of 10 pencils = $ 10
S.P of 10 pencils = C.P of 11 pencils = $ 11
Profit on 10 pencils = 11 – 10 = $1
Profit % = ( 1/ 10) x 100 = 10 %


3.[C]Suppose pipe A alone takes x hours to fill the tank.

Then, pipes B and C will take     x     and     x     hours respectively to fill the tank
                                                  2               4


 1+2+4        =           1

      X                        5
7/X      = 1/5
=> X = 35
 4.[D]From the measure of the length of the sides of the triangle, 9, 40 and 41 we can infer that the triangle is a right angled triangled. 9-40-41 is a Pythagorean triplet.

In a right angled triangle, the radius of the circle that circumscribes the triangle is half the hypotenuse.

In the given triangle, the hypotenuse = 41.

Therefore, the radius of the circle that circumscribes the triangle = 41/2= 20.5 units.
 5.[C]
Clearly, the numbers are (23 x 13) and (23 x 14).
Larger number = (23 x 14) = 322.

 5 A poultry farm has only chickens and pigs. When the manager of the poultry counted the heads of the stock in the farm, the number totaled up to 200. However, when the number of legs was counted, the number totaled up to 540. How many chickens were there in the farm?

 [a] 70
[b] 120
[c] 60
[d] 130
[e] 80

 Answer



1[d]

Let us say Baskar invested $100.

Then, at the end of 'n' years he would have got back $400.

Therefore, the Simple Interest earned = 400 - 100 = $300.

We know that Simple Interest = (Principal * number of years * rate of interest) / 100

Substituting the values in the above equation we get 300 = (100 * n * 8) / 100

Or 8n = 300

Or n = 37.5 years.

2.[d]

To make calculations easy, let us assume that the cost price = $100

The merchant marks his goods up by 50%.

Therefore, his quoted price = cost price + mark up

= $100 + 50% of $100 = 100 + 50 = $150

Now, the merchant offers a discount of 20% on his quoted price

Therefore, amount of discount = 20% of $150 = 20% of 150 = $30

Therefore, he finally sells it for $150 - $30 = $ 120.

We assumed his cost to be $ 100 and he sold it finally for $ 120.

Therefore, his net profit = $ 20 on his cost of $ 100

Hence, his % profit = 20/100 * 100 = 20%.

3[a].

The extra time that the train takes when crossing the platform is on account of the extra distance that it has to cover = length of the platform.

Therefore, length of the platform = speed of train * extra time taken to cross the platform

Length of platform = 72 kmph * 12 seconds

Converting 72 kmph into m/sec, we get 72 kmph = 5/18 = 20 m/sec

Therefore, length of the platform = 20 * 12 = 240 meters.

4.[a]

There are seven positions to be filled.

The first position can be filled using any of the 7 letters contained in PROBLEM.

The second position can be filled by the remaining 6 letters as the letters should not repeat.

The third position can be filled by the remaining 5 letters only and so on.

Therefore, the total number of ways of rearranging the 7 letter word = 7*6*5*4*3*2*1 = 7! Ways.

5[d]

Let there by 'x' chickens and 'y' pigs.

Therefore, x + y = 200 --- (1)

Each chicken has 2 legs and each pig has 4 legs

Therefore, 2x + 4y = 540 --- (2)

Solving equations (1) and (2), we get x = 130 and y = 70.

There were 130 chickens and 70 pigs in the farm.

8.[2]Clearly, marked price of the book = 120% of C.P.

Also, cost of paper = 25% of C.P

Let the cost of paper for a single book be Rs. n.

Then,                120: 25 = 180: n      
                                       n = Rs.  25 x 180 = Rs. 37.50

For the publisher to earn a profit of 25%, S.P. = 125% of C.P.

Also Transportation Cost = 10% of C.P.

Let the S.P. of 5500 books be Rs. x.

Then,         10 : 125 = 82500 : x      
                                x = Rs.   125 x 82500   = Rs. 1031250.
                                                  10

 S.P. of one book = Rs. 1031250   = Rs. 187.50

10[4]printing Cost of book = 20% of C.P.

Royalty on book = 15% of C.P.

Difference = (20% of C.P.) - (15% of C.P) = 5% of C.P.

 Percentage difference     =     Difference       x 100%
                                         Printing Cost

                                         =      5% of C.P.     x 100%

C. Rs. 2000D. None of these


Answer
1.  (c)L.C.M of 5,6,4,3 = 5*6*2 = 120
Required number = 2497/120 = 23

2(a).1201*1201 = (1201)'2 = (1200+1)'2
= 1440000+1+2400 =1442401

 3.(d)Required ratio = 75 +65 : 85+95
                              = 140 : 180
                              = 7 : 9
 4.(c) Required % =[70 + 80]/[95 +110]* 100
                             = 105 /205 *100
                                =73.17%

5.(d)Average sales (in thousand number) of branches B1, B3 and B6 in 2000
           = 80 + 95 + 70 / 3
Average sales (in thousand number) of branches B1, B2 and B3 in 2001
    =105 + 65 + 110 /3
Therefore Required percentage =  245 / 3 /280 / 3 * 100
                                          = 245/280 * 100
                                       = 87.5%

6.(b)Average sales of all the six branches (in thousand numbers) for the year 2000
    = 80 + 75 + 95 + 85 + 75 + 70 / 6
    =80

7.(d)
Total sales of branches B1, B3 and B5 for both the years (in thousand numbers)
    = (80 + 105) + (95 + 110) + (75 + 95)
    = 560.

8(b).let the speed of the stream be x km/hr. Then,
Speed downstream = (15 + x) km/hr,
Speed upstream = (15 - x) km/hr.
30 + 30 = 4 1
(15 + x) (15 - x) 2
900 = 9
225 - x2 2
9x2 = 225
x2 = 25
x = 5 km/hr.

9.(a)
L.C.M. of 21, 36, 66 = 2772.
Now, 2772 = 2 x 2 x 3 x 3 x 7 x 11
To make it a perfect square, it must be multiplied by 7 x 11.
So, required number = 22 x 32 x 72 x 112 = 213444

10.(C)
Let the shares of A, B, C and D be Rs. 5x, Rs. 2x, Rs. 4x and Rs. 3x respectively.
Then, 4x - 3x = 1000
x = 1000.
B's share = Rs. 2x = Rs. (2 x 1000) = Rs. 2000.
