Solution
Step 1: Find the selling price of the socks after discount.
The discount on the socks is 10% of Rs. 200. So, the discount amount is (10/100)*200 = Rs. 20.
Step 2: Subtract the discount from the marked price to get the selling price.
The selling price of the socks after discount is Rs. 200 - Rs. 20 = Rs. 180.
Step 3: Find out how many pairs of socks can be bought for Rs. 45.
Since one pair of socks costs Rs. 180, with Rs. 45, you can buy 45/180 = 0.25 pairs of socks.
Since you can't buy a fraction of a pair of socks, the answer is that you can't buy any pairs of socks with Rs. 45.
None of the options provided (3, 5, 2, 4) is correct.
