Question

Every month, a man spends 72% of his income and saves ₹12,600. Find: (1) his monthly income (2) his monthly expenses

Answer 1

He spends 72%

hence he saves (100-72)=28%

Assume his monthly income=x

Now given x*28%=12600

or 28*(x/100) =12600

hence x=12600*(100/28)

=45000

hence monthly income=45000

& monthly expances=
45000*(72/100)

=450*72

Monthly expenses=₹32400
