Question

There are 1800 students in a school. 800 chose football, 750 chose basketball and the remaining did not choose any game. A student can choose only one game. Find the ratio of the number of students who chose football to the number of students who did not choose any game.

• A. 16:20
• B. 800:250
• C. 16:5
• D. 16:15

Answer 1

The correct option is C

16:5

Total number of students in the school = 1800
Number of students who chose football = 800
Number of students who chose basketball = 750

Number of students who did not choose any game = 1800 - 800 - 750 = 1800 - 1550 = 250

The ratio of the number of students who chose football to the number of students who did not choose any game = $\frac{800}{250}$
= $\frac{16}{5}$
Therefore, the required ratio is 16:5.
