Answer

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
