Two shopkeepers sell the machines at the same list price. The first allows two successive discounts of 30% and 6%; and the second 20% and 16%. Which discount series is more advantageous to the purchaser?
Explanation:
Let the marked price be M
Case I :Shopkeeper No. 1 SP= (0.7) M × (0.94) = 0.658 M
Case I :Shopkeeper No. 2 SP= (0.8) M × (0.84) = 0.672 M
Discount in case I = (1 – 0.658) > discount in case II = (1 – 0.672)
Hence, option (a).
