Question
If P earns Rs. 24,000, she spends 35% of it on rent and Rs.
2,000 on food, saving the remaining amount. Later, her income rises by 25%, while her rent increases by Rs. 600 and her food expenses rise by 15%. How much does P save after these changes?Solution
ATQ;
Amount initially spent by P on rent = 24000 X 0.35 = Rs. 8,400
Increased amount spent on Rent = 8400 + 600 = Rs. 9,000
Amount initially spent by P on food = Rs. 2,000
Increased amount spent on food = 2000 X 1.15 = Rs. 2,300
Increased income of P = 24000 X 1.25 = Rs. 30,000
So, new savings of P = 30000 - (9000 + 2300) = Rs. 18,700
