Directions to Solve
The circle-graph given here shows the spendings of a country on various sports during a particular year. Study the graph carefully and answer the questions given below it.
2.
How much percent more is spent on Hockey than that on Golf?
Answer: Option
Explanation:
Let the total spendings on sports be Rs. x. Then,
| Amount spent on Golf = Rs. |  |
36 | x x |  |
= Rs. | x | . |
| 360 | 10 |
| Amount spent on Hockey = Rs | |
63 | x x | |
= Rs. | 7x | . |
| 360 | 40 |
| Difference = Rs. | |
7x | - | x | |
= Rs | 3x | . |
| 40 | 10 | 40 |
 Required percentage = Rs. |
 |
|
3x/40 | |
x 100 |  |
% = 75%. |
| x/10 |

(Hockey-golf)/golf.
Simply;
When we are finding the difference we should minus the lowest value with the highest value and the answer we got should be divided by the lowest value. This trick works for graphs and piecharts. For pie charts and graphs you will not get the wrong answers using this method.
So,
63 - 36 = 27.
27/36 x 100 = 75%.

@Arpita.
Required percentage = maximum value upon minimum value into 100 (because we have to find that hockey is how much more than golf means increased value].
Maximum value= 3x/10.
Minimum value=x/10.
Maximum/ minimum.
= [3x/10]/ (x/10) *100=75%.

But why should we divide 27/36 and not 27/63? Please tell me.

Why is it 27/36. Why we can't calculate 27/360*100?

The question must be understood as: the ratio between (the difference of spending) and (spending on golf).
Thus difference of spending = 63-36°.
-> ratio = (63-36)/36 = 0.75.
Thus difference of spending = 63-36°.
-> ratio = (63-36)/36 = 0.75.
