Answer 2

Answer:

Rs 5

Step-by-step explanation:

Given,

SP = Rs 7

Profit = 40% of CP = 40% of x

To find,

CP = ? (Let it be x)

We know,

Profit = SP - CP

40% of x = 7 - x

$\frac{40}{100} x = 7 - x$

$\frac{2}{5} x = 7 - x \\ \frac{2}{5} x + x = 7 \\ \frac{7}{5} x = 7 \\ x = 5$

So, CP = Rs 5

Hope that helps
