Answer:
The expected number of children to attend the concert is 143.
Step-by-step explanation:
The total guest expected to attend the concert = 200
Here, Ratio of Adults: Children = 2: 5
Let us assume the common factor in the given ratio = m
So, the expected number of adults to attend the concert = 2 m
Also, the expected number of children to attend the concert = 5 m
Number of (Adults + Children) attending concert = 200
⇒ 2 m + 5 m = 200
or, 7 m = 200
or, m = 200 /7 = 28.57
or, m = 28.57
Now, the expected number of children to attend = 5 m
= 5 x 28.57 = 142.85 ≈ 143
Hence, the expected number of children to attend the concert is 143.
