Let's say X is the first brother's age
x+2 is second brother, and x+4 is the third brother
Since the product of the first and third boy x(x+4) is 20 more than twice (20+x(x+2), our equation is x(x+4)=20+2(x+2)
Simplify from there and see what you get.
Answer:
The size of the population mean would be provided as:
mean +/- std/sqrt(sample size)

<=>
87.3 +/- 1.03
=> Option B is correct.
Hope this helps!
