Answer: The answer is (D) The number of musicians is 3 times the number of athletes.
Step-by-step explanation: Given that the ratio of musicians to athletes in a school is 3 : 1. We are to select the correct statement out of the given four options.
Since the total number of people are not given, so we cannot say that 13 of them are musicians. Therefore, option (A) is incorrect.
If there are 18 people, then number of athletes is given by
[tex]\dfrac{x}{x+3x}\times 18=4.5\neq 12,[/tex]
and hence the option (B) is not correct.
If there are 3 athletes, then
x=3, and so the number of musicians = 3 × 3 = 9 ≠ 12. Therefore, the option (C) is not correct.
Number of musicians = 3x = 3 × x = 3 × number of athletes.
Thus, the correct option is (D) The number of musicians is 3 times the number of athletes.
