A dozen pairs of socks quoted at Rs. 180 are available at discount of 20%. How many pairs of socks can be bought for Rs. 48 ?

A. 3 pairs

B. 4 pairs

C. 2 pairs

D. 5 pairs

Answer: Option B

Solution(By Examveda Team)

Price after discount
= $$\frac{180 × 80}{100}$$
= Rs. 144
Price of 1 pair of socks
= Rs. $$\frac{144}{12}$$
= Rs. 12
Required number of pairs
= $$\frac{48}{12}$$
= 4 pairs
