Let the amount with Radhika be LCM(40,30) = 120
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
Cheers
