The father is 38. The father dies, the mean age of the family is now 14.
How many children are in the family?

2, 3, 4, 5 or 6?

No cheating; no google.

just under 2 and a half....too lazy to figure out the real answer.

*Forgot to mention that the mom's dead.

Any other homework you need help with ?

You can't answer that without knowing the age of the kids and the mother. It's just speculative otherwise. If I had to speculate, I would say 3, cause if the mom is 36, and there are 3 kids of around 10...

I agree, but there is probably some secret catch.

Oooh my mate did that today I think, but his was called the UKMT maths challenge.

Wait...is this something that's like NEML ? you do it in school, like, 6 times a year? I know the NEML thing is just around where I live. New England Math League.

UMKT MC comes first. Kangaroos are selected from UKMT MC rseults.

I got 5, possibly 4.
Here's how I did it:

X = combined age of family members
N = number of family members

Given Data:
X / N = 18
(X-38) / (N-1) = 14

Do some algebra...

x = 14n + 24
(14n + 24) / n = 18

Solve that..
4n = 24
n = 6

That's the total number of people in the family, one of them is the father, leaving 5 left.
Since no mention of the mother is made, either there are just the 5 kids, or one of them is the mother, leaving 4 kids.

14 / 2 = 7

2 kids ages of 7?

No one said it, so... 42?

Mother who is 28 years old with a newborn baby.

I win.
