A tradesman by means of his false balance defrauds to the extent of 20%? in buying goods as well as by selling the goods. What percent does he gain on his outlay?
Correct answer: C. 44%
- A. 20%
- B. 45%
- C. 44%
- D. 48%
Explanation
A 20% advantage while buying makes goods worth Rs.1.20 for every Rs.1.00 spent. A further 20% advantage while selling multiplies this by 1.20, so the return is Rs.1.20 x Rs.1.20/Rs.1.00 = Rs.1.44 per Rs.1.00 outlay, giving a gain of 44%. Students often choose 40% by adding the two 20% gains instead of compounding them.
