You can put this solution on YOUR website!
Let your monthly budget be x
Then you spend 3/5 on food
so cost of food=(3/5)x


you spend 1/4 on bus fare
so cost of bus fare=(1/4)x


The total of these two is $34
so we get,
%283%2F5%29x%2B%281%2F4%29x=34
LCM
%284%283%29x%2B5%281%29x%29%2F20=34
12x%2B5x=34%2A20
17x=680
x=40 dollars
Thats your monthly budget
