Question 145
Ram babu donated 3% of his income to a charity and deposited 12% of the rest in bank. If now he has ₹12804, then his income was:
Solution
Let income = Rs. $$100x$$
Amount left after donation = $$100x-(\frac{3}{100}\times100x)=Rs.$$ $$97x$$
Amount left after depositing in bank = $$97x-(\frac{12}{100}\times97x)$$
= $$97x-11.64x=Rs.$$ $$85.36x$$
According to ques, => $$85.36x=12,804$$
=> $$x=\frac{12804}{85.36}=150$$
$$\therefore$$ Income = $$100\times150=Rs.$$ $$15,000$$
=> Ans - (C)
