Question

After sending 10% of my weekly income to my mother, I spent 25% of the remaining and was left with Rs. 540. Find my weekly income.

Answer 1

Let the weekly income be Rs x
10% of the income is given to his mother
That is amount given to his mother = Rs (x/10)

Given that 25% of the remaining was spent

Given that amount left = Rs 540

∴ x = 800
Thus the weekly income is Rs 800.
