Answer : Each grade level will be 30,60,90,30 respectively.
Explanation:
Since we have given that ratio of freshman to sophomores to juniors to seniors in band is 1:2:3:2
Let the number of fresh man be x
Let the number of sophomores be 2x
Let the number of juniors be 3x
Let the number of seniors be 2x
According to question,
x+2x+3x+2x=240
⇒8x=240
⇒x=[tex]\frac{240}{8}[/tex]
⇒x=30
So, the required number of freshman is 30
Number of sophomores is 2×30=60
Number of juniors is 3×30=90
Number of seniors is 2×30=60
