Question

Zarina said, "The sum of my

age and my father's age is 50.
The product of our ages is 400."
How old is Zarina?

Answer 1

Zarina is 8

Explanation:

this is a little bit of what goes on in my head

400 the product of the ages / 50 her fathers age = ? her age

400 / 50 = 8

but you could also they can each be divided by 10

400 / 10 = 40

50 / 10 = 5

40 / 5 = 8

Zarina is 8 years old

Answer 2

Z + ZF = 50
10 + 40 = 50

Z*ZF= 400
10*40= 400

Z represents Zarinas age and ZF represents her fathers age.
