Question

On selling a bat for Rs 486 a man loses 10%. Find the cost price of the bat.

Answer 1

SP of the bat = Rs 486
Loss = 10%
CP of the bat = $\{\frac{100}{(100-\mathrm{Loss}\%)}\times SP\}$
$$\begin{gathered} =\{\frac{100}{(100-10)}\times 486\} \\ =\frac{48600}{90} \\ =\mathrm{Rs}540 \end{gathered}$$


CP of the bat = Rs 540
