Question

Find the C.P. of an article for which S.P. = ₹ 689 and gain % =6%

Answer 1

Step-by-step explanation:

SP = 689

Gain% = 6%

Let the CP be x

Gain =

$\frac{6}{100} \times x$

A/Q

$x + \frac{6}{100} x = 689 \\ \frac{100x \: + \: 6x } {100} = 689 \\ \frac{106x}{100} = 689 \\ x = \frac{689 \: \times \: 100}{106} \\ x = 650$

Therefore CP = 650
