Question

By selling a watch for Rs. 1500, a man gains $\frac{1}{6}$ of its cost price. Find the cost price of the watch.

Answer 1

$\begin{array}{c}Wehave\\ S.P=Rs.1500\\ gain=\frac{1}{6}ofS.P\\ so,\\ gain=\frac{1}{6}\times 1500\\ =250\\ Now,\cos tprice=S.P+gain\\ =1500+250\\ =Rs1750\end{array}$

Hence, this is the answer.
