Question

A dealer buys a wristwatch for Rs. 225 and spends Rs. 15 on its repairs. If he sells the same for Rs. 300, find his profit percent.

Answer 1

Cost of wristwatch = Rs. 225
Cost on repairs = Rs. 15
Total cost price = Rs. 225 + Rs. 15 = Rs. 240
Selling price = Rs. 300
Gain = S.P - C.P = Rs. 300 - Rs. 240
= Rs. 60
$Gain\%=\frac{Gain\times 100}{C.P}=\frac{60\times 100}{240}=25\%$
