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