Question

Mr. Krishna donates 10% of his income every month and saves 15%. If the toal amount he donates is ₹23000 per month, find his total expenditure.

• A. ₹1,82,725
• B. ₹1,52,250
• C. ₹1,72,500
• D. ₹1,67,500

Answer 1

The correct option is C ₹1,72,500

Let the toal income be ₹x.
$\frac{10x}{100}$ = ₹23000
x = $\frac{23000\times 100}{10}$ = ₹2,30,000
Expenditure = 100 - (10 + 15) = 75% of ₹2,30,000
= $\frac{75}{100}\times 230000$
= ₹1,72,500
