Prev
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
