Question

Find the C.P when S.P = rs 12; gain = 20 %

Answer 1

Answer:

cost price = Rs 10

Step-by-step explanation:

Given selling price (s.p) = Rs 12,

Gain (g) = 20%,

Let cost price = c.p

$c.p = \frac{ s.p \times 100}{100+g}\\=\frac{12\times 100}{100+20}\\=\frac{1200}{120}\\=10$

Therefore,

cost price = Rs 10
