A dozen pairs of gloves of Rs. 180 are available at a discount of 10%. How many pairs of gloves can be bought for Rs. 54?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 4.
Cost of a dozen pairs of gloves after discount = 180 - (10/100) × 180 = 162
Cost of one pair of gloves = 162/12 = 13.5
Number of pairs of gloves that can be bought for Rs. 54 = 54/13.5 = 4
Therefore, 4 pairs of gloves can be bought for Rs. 54.
