A Man sells 11 apples in Rs 97 and incurs a loss of 20%. How many apples can he give to a customer in Rs 96 to make a profit of 10%? Is it possible to solve this question or is it wrong question? Last edited by Ganesh Ujwal; July 2nd, 2018 at 04:18 AM.

The way that is written is very confusing! It's not clear, at first, whether the "Rs 97" is total or per apple. But then it occurred to me that if, selling apples at Rs 97 [I]per apple[/b], he loses money, he certainly could not make a profit by selling at Rs 96 per apple! Suppose the 11 apples cost him Rs c. Selling those 11 apples for a total of Rs 97, this person loses 20% of Rs c. He loses (0.2)c. That is 97 c= 0.2c. Adding c to both sides 97= c 0.2c= 0.8 c. c= 97/0.8= 121.25. That is a cost of 121.25/11= 11.02 Rs per apple. At that rate x apples will cost 11.02x Rs. If he sells those x apples for a total of 96 Rs, he will make a profit of 11.02x 96 Rs. A profit of 10% of his cost would be 0.1(11.02)x= 1.102x Rs. We must have 11.02x 96= 1.102x. Subtracting 1.102x from both sides and adding 96 to both sides, 9.918x= 96. x= 96/9.918= 9.67 apples! That doesn't quite make sense. Last edited by skipjack; July 2nd, 2018 at 09:23 AM.

Ganesh, do you not know someone who is familiar with English to check your problems for proper English before posting them? You are (with most of your problems) losing everybody's time... Remember: this is an ENGLISH site.

Country Boy made a slip. I calculated about 7.9175 apples.

The word "French" colloquially means "swearing", but one of those ten words isn't even regarded as a swear word by some.
