- 1. What is the total number of boys from Colleges E and F together?
Options- A. 215
- B. 251
- C. 283
- D. 310 Discuss
Correct Answer: 215
Explanation:
As per first graph,
The number of students in Collage E = Total number of students x 7%
As per second graph,
The number of girls from College E = Total number of girls x 8%
So number of boys in Collage E = The total number of students in Collage E - The total number of girls in Collage E.
Number of boys from college E = 3500 x 7/100 - 1800 x 8/100
Number of boys from college E = 35 x 7 - 18 x 8
Number of boys from college E = 245 - 144 = 101
Similarly for collage F also apply the same formula.
Number of boys from college F = 3500 x 12/100 - 1800 x 17/100 = 420 - 306 = 114
Hence, the total number of boys together in collage E and F = 101 + 114 = 215- 2. What is the speed of the boat in still water?

Explanation:
From above given table ,
Total number of students in II = 100 + 200 + 200 + 100 + 100 + 100 + 100 = 900
Total number of students in I = 200 + 300 + 500 + 100 + 400 + 300 + 200 = 2000
? Required ratio = total number of students in II : total number of students in I
Required ratio = 900 : 2000 = 9 : 20- 6. If the total amount spent on sports during the year was Rs. 1,20,00,000. how much was spent on basketball?
