Kojo is twice as old as Esi who in turn is 5 years older than Kweku. If their total age is 47 how old is each of them

Answer 1

Let's say Kweku's age is x.
Esi's age is x + 5.
Kojo's age is 2 * (x + 5) = 2x + 10.

The total age of the three is x + x + 5 + 2x + 10 = 4x + 15.
Since their total age is 47, we have 4x + 15 = 47.
Subtracting 15 from both sides gives 4x = 32.
Dividing both sides by 4 gives x = 8.

So, Kweku's age is x = 8 years.
Esi's age is x + 5 = 8 + 5 = 13 years.
Kojo's age is 2x + 10 = 2 * 8 + 10 = 16 + 10 = 26 years.

Therefore, Kweku is 8 years old, Esi is 13 years old, and Kojo is 26 years old.
