Answer 1

Answer:

I think the answer is 6............

Answer 2

Answer:

5

Step-by-step explanation:

Father's age = x in 2003

In 2003, Farah's age is 0.1x

In 2018, her father will be x + 15

Farah will be 0.1x + 15

We know that in 2018, Farah is 0.4x

So,

0.1x + 15 = 0.4x

0.4x - 0.1x = 15

0.3x = 15

x = 50

So Farah in 2003 is 0.1 x 50 = 5 years old
