Find the single discount equivalent to two successive discounts 50% and 49%.
The correct option is D (74.5)%
Let the marked price of an article be Rs. 100 and
Given two given successive discounts d1=50% and d2=49%
Then, S.P = M.P×100−d1100 × 100−d2100
=100×100−50100 × 100−49100
=100×50100 × 51100
=25510
=Rs. 25.5
∴ Single equivalent discount =100−25.5=74.5%
Hence, a single discount of 74.5% is equivalent to two given successive discounts.
