A coolie deposits Rs 150 per month in his post office Savings Bank account. If thisis 15% of his monthly income, find his monthly income.

Answer:

Let the monthly income of a coolie be ‘x’

Here, coolie deposits Rs 150 per month which is 15% of his monthly income

From the above we can derive that,

x × (15/100) =150

Which implies, x = (150 × 100) / 15

x = 15000/15

x = 1000

∴ Monthly income is Rs 1000
