    the ratio means that there are 1 25p coin, 2 10p coins, 3 5p coins. Now how much rupee is there in total? According to ratio 1:2:3, total rupee 1*25+2*10+3*5 =60p So if there are 60 pence in total, there are 2 10p coins. Now convert 30rs to pence and find out, using the unitary method, the number of 10p coins when there is 30rs.
    Hope this helps.
