A boy buys 12 pencils for Rs. 10 and sells 10 pencils for Rs. 12. Find his gain percentage.
A. 44%
B. 42%
C. 45%
D. 40%
Answer: Option A
Solution (By JKSSB Mock Tests)
Cost Price of 1 pencil = 10 / 12 = 5 / 6. Selling Price of 1 pencil = 12 / 10 = 6 / 5. Profit = (6 / 5) - (5 / 6) = (36 - 25) / 30 = 11 / 30. Profit percentage = ((11 / 30) / (5 / 6)) * 100 = (11 / 25) * 100 = 44%.
