Answer 1

Answer:

okay

Step-by-step explanation:

Let the number of 20 paise coins be x and the 25 paise coins be y.

=> 20x + 25y = 1150.

=> 4x + 5y = 230____(1)

Given that she has 50 coins in total.

=> x + y = 50. _____(2)

On solving (1) & (2) * 4, we get

4x + 5y = 230

4x + 4y = 200

______

y = 30

Substitute y = 30 in (2), we get

=> x + y = 50

=> x + 30 = 50

=> x = 20.3

Therefore the number of 20 paise coins =

20.

Therefore the number of 25 paise coins

30.
