Question

a is two years younger than b who is twice as old as c if the total of the ages of a b and c is 28 years how old is b
​

Answer 1

Answer:

12 yrs old

Step-by-step explanation:

a is 2 yrs younger than b therefore  a= b-2

b is twice as old as c therefore b= 2c

so, a = 2c-2

a+b+c=28

2c-2 + 2c + c = 28

5c - 2 = 28

5c = 30

c = 6

b = 2c so, b is 2 x 6      12 years old
