If price of an apple is reduced by 30 Percent it enables the customer to buy 5 more apples for Rs.140. Find the reduced rate of apple.
Answer & explanation
Correct answer: option 4
30% = \(\frac{3}{10}\)
Price 10 : 7
Quantity 7 : 10
{ Price ∝ \(\frac{1}{Quantity }\)}
(10- 7)R = 3R = 5
10R = \(\frac{5}{3}\) × 10 = 16.66
Reduced price of apple = \(\frac{140}{16.66 }\) = Rs8.4
