Question

By selling 90 ball pens for Rs. 160, a person loses 20%. How many ball pens should be sold for Rs. 96 so as to have a profit of 20%?

A. 36

B. 40

C. 24

D. 32

Answer: Option A

Solution (By JKSSB Mock Tests)

SP of 90 pens = 160. SP of 1 pen = 160/90 = 16/9. Loss = 20%, so CP of 1 pen = (16/9) / 0.8 = 20/9. Desired SP for 20% profit = 1.2 * (20/9) = 24/9 = 8/3. Number of pens for Rs. 96 = 96 / (8/3) = 96 * 3 / 8 = 36.
