Answer 1

Answer:

Rs 19.20

Step-by-step explanation:

Buying price = Rs 20

Profit = 20% = 0.20 × 20 = Rs 4

Selling price = buying price + profit = Rs 20 + Rs 4 = Rs 24

He wants to make a 25% profit.

Let's say he should buy the pen at Rs 'a' in order to make that amount of profit.

∴ a + $\frac{25}{100} a$ = 24

1.25a = 24

a = $\frac{24}{1.25} = 19.20$

So he should buy the pen at Rs 19.20
