Correct option is C
Given: Desired gain = 17% Discount = 22%
Formula Used:
Let the marked price (MP) be M. Selling Price (SP) after discount = MP * (1 - Discount/100) Gain% = (SP - CP)/CP * 100
Solution:
Let the CP = 100
SP = 100×117/100=117
MP = 117×100/78=150
Required percentage =(150-100)/100×100=50%
