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

Have a nice day
