Answer 2

Answer:

number of 25 paisa coins = 80

number of 50 paisa coins = 60

Step-by-step explanation:

Let the number of coins of 25 paisa be X

then the number of coins of 50 paisa will be 140-X

As 4 coins of 25 paisa make Rs. 1

and 2coins of 50 paisa make Rs. 1

So

X / 4 + ( 140 - X ) / 2 = 50

Multiplying by 4 we get

X + 2( 140 - X ) = 200

X + 280 - 2X = 200

- X = 200 - 280

- X = - 80

X = 80 ........... number of 25 paisa coins

The number of coins of 50 paisa will be 140-X

= 140 - 80

= 60 ........... number of 50 paisa coins

Tally

80 /4 + 60 / 2

= 20 + 30

= 50
