Bala spent 7/12 of his savings on 48 stamps and 12 coins.The cost of a stamp was 1/3 that of a coin.Then he bought another 5 coins and some stamps with the remainder of his savings.How many stamps did he buy altogether?
cost of 1 stamp=cost of 3 coins
12 coins=12x3=36
7/12=48+36=84 stamps
1/12=84 divide by 7=12 stamps
5/12=12x5=60 stamps
5 coins=5x3=15
60-15=45 stamps
total number of stamps=48+45
=93
answer=93 stamps
