Question

6. On Marika's 8th birthday, in 2004, her father said, "My age is now four times your age."

In what year will Marika's father be able to say, "My age is now three times your age," on
Marika's birthday?

Answer 1

2008

Explanation:

when she is 12 (4 years after 2004) her dad will be 36, which is 3 x 12, therefore, in 2008 he will be able to say this.

Answer 2

2008

Explanation:

The difference in their ages is ...

4m -m = 3m = 3(8) = 24 . . . years (Marika was 8 in 2004)

__

Marika's age when the father was 3 times her age was ...

3m -m = 2m = 24 . . . years

m = 12 . . . . . Marika was 12 when her father was 3 times her age

That is 12 -8 = 4 years from 2004, so it will be true in 2008.
