Profit and Loss Practice Test 1

Let CP of tape recorder = x
A sold it to B = Rs 4,860 at a loss of 19%
CP of the tape recorder $=\mathit{x}-\frac{19\times \mathit{x}}{100}=\frac{81}{100}\mathit{x}$
$\frac{81}{100}\mathit{x}=4860$
$\mathit{x}=6000$
CP of the tape recorder = Rs 6,000.
B sold it to C that profit of A = 17%
Profit of A $=\frac{17\times 6000}{100}=1020$
C’s cost price on tape recorder = 6,000 + 1,020 = Rs 7,020
Gain per cent of B $=\frac{7020-4860}{4860}\times 100=44\frac{4}{9}\%$
