Answer 1

Given :

• A cooler deposits rs 150 per month in his post office savings bank account if this is 15% of his monthly income

to find :

• his monthly income

Solution:

Let the monthly income of a coolie be 'x'

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

From the cooler above we can derive that,

x × (15/100) = 150

Which implies,

x = (150 x 100)/15

x = 15000/15

x = 1000

Monthly income is Rs 1000
