Question

A is two years older than b who is twice as old as c if total age of a b and c is 27 how old is b

Answer 1

let c's age be x then b's age be 2x and a age 2x+2
a/q
x+2x+2x+2=27
5x+2=27
5x=25
x=5 =c's age then b's age =2x=2×5=10

Answer 2

$\huge\bold{\green{{SOLUTION}}}$

Let C's age be x years.

Then, B's age = 2x years and 

A's age = (2x + 2) years

Given, 2x + 2 + 2x + x = 27

⇒ 5x + 2 = 27

⇒ 5x = 27 − 2 = 25

⇒ x = 5

∴ B's age = (2×5) years = 10 years.
