Question
When a shopseller offers a discount of d% on item A and
(d + 5)% on item B, quoting an equal marked price on both the items. If the ratio of S.P of item A to that of B is 18:17, then what will be the discount % offered on item A and item B individually.Solution
ATQ, Let the Marked price of item A and item B be Rs.100 each. Given that discount on A is d% and discount on B is (d + 5)% Only from choice (3) we get that answer. Discount on Item A = 10% of 100 = 10. SP of A = 100 - 10 = 90 Discount on Item B = 15% of 100 = Rs.15 SP of B = 100 - 15 = 85 The ratio of SP of A & B = 90:85 = 18/17 which satisfies the given condition by taking 10% and 15% discounts on items A and B.
