    Directions (Q. 76 - 80): Study the following graph carefully and answer the questions given below: Percentage profit earned by the company over the years Percentage profit\[\text{=}\frac{\text{Income-Expenditure}}{\text{Expenditure}}\text{ }\!\!\times\!\!\text{ 100}\]  

    If the expenditures of the company in the year 2014 and 2012 were Rs. 55500 each then what was the difference between the income of the company in the year 2012 and that in 2014?

    A)  Rs. 3215                      

    B)  Rs. 4375          

    C)         Rs. 2175          

    D)         Rs. 3891

    E)  Rs. 2775            

    Correct Answer: E

    Solution :

    \[\frac{\text{Income}}{\text{Expenditure}}\text{=}\frac{\text{100+ }\!\!%\!\!\text{ Profit}}{\text{100}}\] \[\therefore \]\[\text{Income=Expenditure}\left( \frac{\text{100+ }\!\!%\!\!\text{ profit}}{\text{100}} \right)\] \[\therefore \]Income in 2012\[=55500\left( \frac{100+15}{100} \right)\] \[=55500\times \frac{115}{100}=Rs.\,\,63825\] Similarly, income in 2014 \[=55500\left( \frac{100+20}{100} \right)=55500\times \frac{120}{100}\] \[=Rs.\,\,66,600\] Required difference\[=Rs.(66,600-63,825)\] \[=Rs.\,\,2775\] Another Method: Required difference\[=55500\times \frac{(120-115)}{100}\]             \[=555\times 5=2775\]
