Let 50 paise coins be x in number.
Therefore 25 paise coins are 2x in number.
Value of 50 paise coins is 50x and value of 25 paise coins is 25 x 2x = 50x.
Total value is 900 paise.
Therefore, 50x + 50x = 900.
100x = 900.
x = 9.
Therefore, no. of coins of 50 paise is 9 and no of coins of 25 paise is 18.
Total coins = 27.
