Correct Answer - Option 3 : 8
Given:
A shopkeeper sells a dozen pair of socks whose marked price is Rs. 600 at 20% discount.
Concept used:
Profit and loss
Calculation:
20% discount is offered on Rs.600
SP = 600 - (20% of 600)
SP = 600 - 120
SP = Rs.480
Selling price of one pair of socks = 480/12
SP = 40
AS per the question,
⇒ 320/40 = 8
8 pair of socks can be bought for Rs.320
