Show answer & explanation

Correct answer: D

Explanation

The correct answer is option 4 i.e. 70%

Understanding Application

MP - 20% Of MP = SP

0.8MP = SP

0.8MP = CP + 36% Of CP

0.8MP = 1.36 CP

MP/CP = 1.36/0.8 = 17/10

MP is what % more than CP = (MP - CP) × 100/CP

7 × 100/10 = 70%

MP - Discount = SP

SP - Profit = CP
