Ram babu donated 3% of his income to a charity and deposited 12% of the rest in bank. If now he has Rs. 12804, then his income was :

Let Ram Babu’s salary be Rs. p. Remaining amount after donations to charity

= Rs.	97p
	100

After depositing money in the bank,

Remaining amount =	97p	×	88
	100		100

∴	97p × 88	= 12804
	10000

⇒ p =	12804 × 10000	= Rs. 15000
	97 × 88
