Answer 2

Answer:

$\sf \huge \green {\therefore \: C.P. = ₹600}$

Step-by-step explanation:

S.P. = ₹678

Gain% = 13%

$\sf C.P. = \frac{100}{100 + P\%} \times S.P.$

$\sf C.P. = \frac{100}{100 + 13} \times ₹678$

$\sf C.P. = \frac{100}{ \cancel{113}} \times ₹ \cancel{678}$

$\sf C.P. = 100 \times 6 = ₹600$
