This problem is for MENTAL solution. 

You can combine (group) your coins in sets, each containing one 50-paise and two 25-paise coins.


Then each group worth ONE rupee.


How many such groups are there in your collection ?  - The answer is obvious: 34.


Hence . . . 



Should I continue ?   Or everything is just clear to you ??
