Answer 2

Given:

Spending on house rent=20%

Spending on house expenses=75% of the balance

Balance at the end of the month=Rs.250

To find:
The monthly earning of the man in rupees

Solution:

The monthly earning of the man in rupees is 1,250.

We can find the earnings by following the given steps-

Let us assume that the monthly earning of the man is Rs. X.

Now, we know that he spent 20% of his earnings on rent.

So, the remaining amount=Total earnings- spending on rent

=X-20% of X

=X-20X/100

=80X/100

The man spends 75% of the remaining balance on other expenses of his house.

So, the amount spent on other expenses=75% of 80X/100

=75/100 of 80X/100

=3/4×8X/10

=6X/10

Now, the balance remaining at the end of the month=80X/100-6X/10

=8X/10-6X/10

=2X/10

=X/5

This amount is equal to Rs.250.

On equating, we get

X/5=250

X=250×5

X=1,250

Therefore, the monthly earning of the man in rupees is 1,250.
