Answer 1. 5)  54671-14456-33466  = 6749

            2.1)5220×15÷2175 = 36

            3.5)12.5 × 3.2 × 8.8 = 352

             4.5) ? × 22/100 = 340-166.64  
           => ? = 173.36 × 100/22 = 788  

          5 3) .23/100 ×  ? = 45/100 × 816 - 240.7
          ? = 126.5 × 100/23 = 550

         6.3)  12 Women  complete a piece of work in 5 days
        there fore, 6 Women  complete a piece of work in 10 days
             Given that    3 Women  & 9 Children  complete a piece of work= 10 days   {1women= 2Children 
                  So,18 children complete the same  piece of work in 10 days
                 so,  36 children complete the same piece of work  in 5 days

  7.4).Speed downstream = (13 + 4) km/hr = 17 km/hr
      Time taken to travel 68 km downstream =  68 /17    hrs = 4 hrs.  

 8.1)Let the investment in scheme A be Rs.xand
 the investment in scheme B be Rs.(13900 - x)
We know that SI = PRT/100
Simple Interest for Rs.x in 2 years at 14% p.a. = x×14×2/100=28x/100
Simple Interest for Rs.(13900 - x) in 2 years at 11% p.a. = (13900−x)×11×2/100=22(13900−x)/100
Total interest = Rs.3508
28x/100+22(13900−x)/100=3508
28x+305800−22x=350800
6x=45000
x=45000/6=7500
Investment in scheme B = 13900 - 7500 = Rs.6400

 9.1)Regular working hours in 4 weeks = (4 × 6 × 10) = 240 hours

Amount earned by working in these regular working hours
= 240 × 2.10 = Rs.504

Additional amount he earned = 525 - 504 = Rs.21

Hours he worked overtime = 21/4.2 = 210/42 = 5 hours

Total hours he worked = 240 + 5 = 245 hours

10.1)Each number is twice the previous one with 1 added or subtracted alternatively.
