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\[\text{=}\frac{\text{Income-Expenditure}}{\text{Expenditure}}\text{ }\!\!\times\!\!\text{ 100}\]
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\[=55500\times \frac{(120-115)}{100}\] \[=555\times 5=2775\]You need to login to perform this action.
