Question
When the price of apples is decreased by 30%, a customer
is able to purchase 5 additional apples with Rs. 140. Determine the original price per apple.Solution
Let the previous price of apple be Rs. '10x' per piece So, new price of the apple = '10x' X 0.7 = Rs. '7x' ATQ: (140/7x) - (140/10x) = 5 or, (20/x) - (14/x) = 5 or, 6/x = 5 or, 5x = 6 x = 1.2 So, previous price of apples = 10 X 1.2 = Rs. 12 per pieceÂ
