f:so:j:s = 1:3:4:6
4x=j=60
x=15
total = 15 + 45 + 60 + 90 = 210

Solution


Given:
    • The ratio of freshmen to sophomores to juniors to seniors in the athletic team = 1: 3: 4: 6
    • Number of juniors in the team = 60

To find:
    • The total number of students in the team

Approach and Working:
    • Let us assume that 14x as the total number of students in the team (Since, 1 + 3 + 4 + 6 = 14)
    • Thus, number of juniors = 4x = 60
      o Implies, x = 15
    • Therefore, total number of students in the team = 14 * 15 = 210

Hence the correct answer is Option E

Answer: E

A. 90
B. 140
C. 150
D. 180
E. 210


The entire ratio can be expressed as: 1x + 3x + 4x + 6x = total. For the juniors, we can create the equation:

4x = 60

x = 15

So there are 1x + 3x + 4x + 6x = 14x = 14(15) = 210 students on the team

Answer: E
