Let the number of fifty paise coins = x
Therefore the number of twenty five paise coins
=
2x
Value of fifty paise coins = x x 50 paise = Rs.
50x 100 X 2 Rs.
Value of twenty five paise coins = 2x × 25 paise
25 100 = 2x x X 4-Rs. V 2 = 2x x
X 2 X 2 Total value of all coins = Rs.(
But the total value of the money is Rs.9
X2 2 X 9
2x 2
..x = 9
Therefore number of fifty paise coins = = x=9 Number of twenty paise coins 2x = 2 x 9 = 18
