A watch was sold at 15% loss. If the selling price was Tk. 8 more, then the seller could have made a profit of 10%. What was the purchese price of what watch?

A 45

B 32

C 36

D 30

Correct Answer: Option B

Let purchase price of the watch be= x

Then, at 15% loss, the selling price is= (1- 0.15)x = 0.85x

And, at 10% profit, the selling price is= (1+0.10)x = 1.10x

Difference between two selling price = 110x - 85x = 0.25x

A/Q,

0.25x = 8

or, x = 8/0.25 = 32
