Question

Sameera spent 90% of her income and donated 3% for socially useful causes. If she was left with ₹ 1750 at the end of the month, what was her actual income ?

Answer 1

Let the actual income of Sameera be ₹ x. 

Sameera spent 90% of her income and donated 3%. 

∴ Sameera’s total expenditure 

= (3% + 90%) of x 

= 93% of x 

= \(\frac{93}{100}\) × x 

= 0.93x 

Now, Savings = Income – Expenditure 

∴ 1750 = x-0.93x 

∴ 1750 = 0.07x

\(x=\frac{1750}{0.07}\) = \(\frac{1750\,\times\,100}{0.07\,\times\,100}\) = \(\frac{175000}{7}\) = 25000

∴ The actual income of Sameera  is ₹ 25000.
