Comment below if any doubt occurs.
In question no.15 I have written money spent is 75% of x but it is 72 % of x.
I am sorry for that.But I am correcting it here.
After correction the equation would be:-
x-72/100x=7200
100x/100-72x/100=7200
28x/100=7200
28x=7200×100
28x=720000
x=720000/28
x=180000/7
So the his total monthly income was Rs.180000/7
