Question

The cost price of a pen is ₹ 12. But the shopkeeper sold it for ₹ 18. Then, find the percentage of profit obtained by the shopkeeper.

Answer 1

We have,
Profit = S.P - C.P = ₹ 18 - ₹ 12 = ₹ 6
$\left[1mark\right]$

We know,

a% of C.P. = Profit

$\frac{a}{100}\times 12=6$

$a=\frac{6}{12}\times 100$

$a=50$%

Therefore, the percentage of profit obtained by the shopkeeper is 50%.
