Question

Chris is 32 years old. Chris is 4 years younger than twice his sister Sarah's age. Option 1: Sarah is 14 years old Option 2: Sarah is 16 years old Option 3: Sarah is 18 years old Option 4: Sarah is 20 years old

Answer 1

3. Sarah is 18 year old

Explanation:

Let Sarah's age be x

Chris's age = 32 (given)

2x - 4 = 32 (twice the age of Sarah less 4 years is equal to Chris's age)

2x = 32 + 4

x = 36 / 2 = 16

So Sarah is 16 years old

Answer 2

32-4=28
28:2=14
Answer is 14
