Question

When a man spends 5/9 of his monthly income he saves 3600 a month. Find his income.

Answer 1

Answer:

His monthly income is 8100 rupees...

Step-by-step explanation:

Let monthly income be 'x'

amount spent = 5/9 * x

amount saved = 3600

amount spent + amount saved= monthly income

5x/9 + 3600=x

3600 = x-5x/9

         = (9x-5x)/9

         = 4x/9

3600 = 4x/9

==> x=8100
