Correct Answer - Option 3 : 28.57%
Given:
An offer of “Buy 5 Get 2 free” is given.
Concepts used:
M.P. = S.P. + Discount
Discount % = Discount/M.P. × 100
Calculation:
Let M.P. of 1 good be Rs. x.
M.P. of 7 goods = 7x
Discount on 7 goods = Rs. 2x
⇒ Discount on 1 good = Rs. 2x/7
⇒ Net discount % = {(2x/7)/x} × 100 = 28.57%
∴ Net discount is equal to 28.57%.
