Let number of 25p coins be x .
No. of 50p coins = 80-x.
Now,
25*x + 50(80-x) = 25*100
25x + 4000 - 50x = 2500
25x = 1500
x = 1500/25 = 60.
Thus, No. of 25 paise coins is 60 and
No. of 50 paise coins will be 80-60 = 20 .
No. of 50p coins = 80-x.
Now,
25*x + 50(80-x) = 25*100
25x + 4000 - 50x = 2500
25x = 1500
x = 1500/25 = 60.
Thus, No. of 25 paise coins is 60 and
No. of 50 paise coins will be 80-60 = 20 .
