Rajesh sells taperecorder to Mihir at a loss of $10 \%$ and Mihir sells it to Shiv at a loss of $20 \%$. If Shiv pays $Rs.\,1440$ for it, at what price did Rajesh buy? (in $Rs.$)

A

B

$2000$

C

$1800$

D

None of these

Solution

We have, $m=-10, n=-20, z=₹ 1440$

$\therefore \quad$ Cost price of tape-recorder for Rajesh

$=\left[\frac{100^{2} z}{(100+m)(100+n)}\right]$

$=\left[\frac{100 \times 100 \times 1440}{(100-10)(100-20)}\right]$

$=Rs. 2000$
