| Arun spends 35% of his salary on food, 15% on house rent, 10% on conveyance and incurs 20% on miscellaneous expenditure. If he still manages to save Rs. 2500, then his annual salary is |
A) Rs. 150000
B) Rs. 100000
C) Rs. 200000
D) Rs. 175000
Correct Answer: A
Solution :
| Let the monthly salary be Rs. x. |
| Then, saving |
| Then, saving= [100 – (35 + 15 + 10 +20)]% = 20% |
| \[\therefore \]\[\frac{20x}{100}=2500\] |
| \[\Rightarrow \]\[x=\frac{2500\times 100}{20}=\text{Rs}\text{. 12500}\] |
| Annual salary \[=12500\times 12=150000\] |
