| Directions: Study the graph carefully and answer the questions given below it. |
| Spendings of a country on various sports during a particular year |
 |
| How much per cent more is spent on hockey than that on golf? |
A) 27%
B) 35%
C) 37.5%
D) 76%
E) None of these
Correct Answer: D
Solution :
| Let the total spendings on sports be Rs. a. Then, |
| Amount spent on golf \[=\text{Rs}\text{. }\left( \frac{36}{360}\times a \right)=\text{Rs}\text{. }\frac{a}{10}\] |
| Amount spent on hockey \[=\text{Rs}\text{. }\left( \frac{63}{360}\times a \right)=\text{Rs}\text{. }\frac{7}{40}a\] |
| Now, difference \[=\text{Rs}\text{. }\left( \frac{7a}{40}-\frac{a}{10} \right)=\text{Rs}\text{. }\frac{3a}{40}\] |
| Hence, required percentage |
| \[=\,\left[ \left( \frac{3a/40}{a/10} \right)\times \,100 \right]\]% = 75% |
