Let numbers of 50 paise coins be x and 25 paise coin be y then A.T.Q.
x+y=30
y = 30-x......... 1
50x+25y=1100.......2
Substituting 1 in 2
50x+25(30-x) =1100
50x+750-25x=1100
25x=1100-750=350
x = 350/25 =14
Therefore y=16
Hence the number of 50 paise coins are 14 and number of 25 paise coins are 16.
