Question 139

A reduction of 20% in the price of an apple enables a man to buy 10 apples more for 54. The reduced price of apples per dozen is

Solution

let the price per apple be Rs P

and Number of apples be N

PN = 54

Now reduction in price by 20% , the new price = 0.8 P

and due to reduction a person can buy 10 more apples in same price

0.8P(N+10) = 54

0.8 x 54 + 8P = 54

8P = 10.8

P = Rs 1.35

cost of 12 apples after reduction in price = 12 x 1.35 x 0.8 = Rs 12.96
