**Answer :**

20 paisa coins : 200

25 paisa coins : 124

Explanation:

Let the number of 20paisa coins be Y,

then number of 25paisa coins = 324-Y

0.20 * Y + 0.25 * (324 - Y) = 71

> 20Y + 25 * (324 - Y) = 7100 (Multiply both sides by 100)

> -5Y + 8100 = 7100

> 5Y = 1000

> Y = 200

So no of 20paisa coins = 200

and no of 25paisa coins = (324 - Y) = 124
