You can, for example never foretell what any one man will do, but you can say with precision what an average number will be up to!
Let the amount with Radhika be LCM(40,30) = 120vinay1983 wrote:
Price of 1 pineapple = 120/40 = 3
Price of 1 apple = 120/30 = 4
She retains 15% of 120 = 15/100*120 = 18
Remaining money = 120 - 18 = 102
Price of 14 pineapples = 14*3 = 42
Money left = 102 - 42 = 60
Number of apples she can buy with 60 bucks = 60/4 = 15
Choose C
