A shopkeeper sells goods at a profit of 12% and uses a weight which is 15% less than the original weight. Find his total percentage gain. (Correct to 2 decimal places)
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1i.e. 31.76%
Given that
He sells an article at a profit of 12% = 12/100 = 3/25
He uses a false weight of 15% = 15/100 = 3/20
According to the question
25: 28 (12% profit)
17 : 20 (15% less wieght)
Net ratio = 85: 112
Total % gain = [(112 - 85)/85] × 100 = (27/85)×100 = 31.76 %
