1 answer:
Answer:
150 boys were enrolled in 2012
Step-by-step explanation:
Let the number of boys enrolled in 2012 be x
Let the number of girls enrolled in 2012 be x + 200
Ratio of boys to girls in 2012 enrollment = 3/7
Now;
3/7 = x/x + 200
7x = 3(x + 200)
7x = 3x + 600
7x - 3x = 600
4x = 600
x = 600/4
x = 150 boys
Hence, 150 boys were enrolled in 2012
