Question

Alice and malice are twins. they have a brother bob who is 8 years older. if the sum of their ages is 23, find the ages

Answer 1

Alice's age = 5 years

Malice's age = 5 years

Bob's age = 5+8 =13 years

Explanation:

Let x be the age (in years of Alice and Malice (They have the same age because they are twins).

Age of Bob: x+8 (because he is 8 years older than the twins).

Then the sum of their three ages is 23:

x (Alice's age) + x (Malice's age) +(x+8 ) (Bob's age)= 23

2x + ( x+8) = 23

3x+8 = 23

3x = 15

(3x)/3 = 15/3

x = 5

So ...

Alice's age = 5 years

Malice's age = 5 years

Bob's age = 5+8 =13 years
