Question

Every month,a man spends 72% of his inco.e and saves 12,600 rupees.Find: his monthly income and his monthly expenses

Answer 1

Let his salary be x.
(100-72)% of x =12,600 Rs.
28x/100= 12600
x=45,000rs
expenses = 45000-12600=32400

Answer 2

if he spends 72percent the saving will be 28percent
then we have to divide 12600 from 28
12600÷28=450
then 1percent of his salery=450
then total salery=450×100=45000
