Question

Rajesh sells a tape recorder 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 it?

• A. Rs 1920
• B. Rs 2000
• C. Rs 1800
• D. Rs 2332
• E. None of the above

Answer 1

The correct option is B Rs 2000

We have, m =-10,n =-20, z =Rs 1440.
$\therefore$ Cost price of the tape recorder for Rajesh
$=\left[\frac{{100}^{2}z}{(100+m)(100+n)}\right]=\left[\frac{100\times 100\times 1440}{(100-10)(100-20)}\right]=Rs2000$
