4 years after Jumbo the elephant was born, Gumbo was born.

4 years later, Mumbo was born.

J + 4 = G, G + 4 = M

J + 8 = M

Now, Jumbo is 5 times as old as Mumbo.

J = 5M

If M = 2, J = 10

Answer choice:

a) 2

if the math is too confusing for you, and the problem IS multiple choice, just try each answer.

If Mumbo is 2, and Jumbo is 5 times as old, then Jumbo would be 5X2=10.

That works correctly, because then Gumbo would be 10-4=6.

So you have all 3 ages working with the given conditions:

Jumbo = 10

Gumbo = 6

Mumbo = 2

each 4 years apart and Jumbo is 5 times as old as Mumbo.

So, YES, answer a) 2.

4 years after Jumbo the elephant was born, Gumbo was born

j = g + 4

4 years later, Mumbo was born.

g = m + 4

In j = g + 4 Substitute for g = m + 4

j = (m + 4) + 4

j = m + 8

Now, Jumbo is 5 times as old as Mumbo

j = 5m

Set the last two equations equal

5m = m + 8

4m = 8

m = 2 <–––––– answer a
