Directions: The following pie chart represents the amount spent on different sports by a school in a calendar year. If the amount spent on football is ₹ 9,000, answer the following questions :
What is the total amount spent on all the sports ?
₹ 72,000
The whole pie chart represents the total spending on all the sports, so the total is simply the value of the complete 360°.
Football covers 45° and stands for ₹ 9,000, so one degree is worth \(\frac{9{,}000}{45} = 200\) rupees.
The total is therefore \(360 \times 200 = 72{,}000\).
A quick check confirms this: Football 45°, Hockey 100°, Cricket 160°, Tennis 35° and Basketball 20° add to exactly 360°, so nothing has been left out.
Hence, the total amount spent on all the sports is ₹ 72,000.
Institute D reduces the number of candidates trained by 20%, while increasing the fee per candidate by 25%. What will be the fee collected by Institute D after the changes ?
If Institute B increases its fee per candidate by 25%, while the number of candidates remains unchanged, what will be the new total fee collected by all five institutes ?
By how much does the weighted average training fee per candidate for institutes that trained 250 or fewer candidates exceed that for institutes that trained more than 250 candidates ?
If the total amount spent on Football increases from ₹ 9,000 to ₹ 18,000 (and the pie chart remains unchanged), the combined amount spent on Hockey and Basketball is :
What is the amount spent on Basketball ?
What fraction of the total amount is spent on Cricket ?
What is the total fee collected by all five institutes ?
The combined fee collected by Institutes A and C is in what ratio to the combined fee collected by Institutes D and E ?
How much more is spent on Hockey than on Football ?
