let no. of 25p coins be 3x
50p coins be x
denomination of 25p coins=3x*25=75x
denomination of 50p coins=x*50=50x
75x+50x=total money (in paise)
125x=5000
x=5000/125=40
no. of 25 p coins=3x=3*40=120
no . of 50p coins=x=40
check-
denomination of 25p coins=120*25=3000p=Rs.30
denomination of 50p coins=40*50=2000p=Rs.20
total money=20+30=50
hope it helps
