The monthly income of a person was Rs. 13500 and his monthly expenditure was Rs. 9000. Next year his income increased by 14% and his expenditure increased by 7%. The per cent increase in his savings was

A) 7

B) 21

C) 28

D) 35

Correct Answer: C

Solution :

Original saving = Rs. \[(13500-9000)\]= Rs. 4500

New income = 114% of Rs. 13500

= Rs. \[(114\times 135)\]= Rs. 15390

New expenditure = 107% of Rs. 9000= Rs. \[(107\times 90)\]= Rs. 9630

New savings = Rs.\[2001=45+45+40+55+55+40\]= Rs. 5760

\[\therefore \]Percentage increase in savings

\[=\frac{5760-4500}{4500}\times 100=\frac{1260}{45}=28%\]
