1 Rupee = 100 paise

30Rs = 3000 paise

25p : 10p : 5p = 1 : 2 : 3

25*X + 10*2X + 5*3X = 3000

60X = 3000

X = 50

25*50 = 1250

10*2*50 = 1000

5*3*50 = 750

sum of 1250,1000,750 is 3000. Just to verification

750 is the number of paise which we got adding all the 5 paise coins

so number of 5 paise coins = 750/5 = 150 coins.
