Question

Charles is eight years older than five times Mark’s age. If Charles is 63 years old, how old is Mark?

Answer 1

Answer:

Mark is 11 years old.

Explanation:

Given:

• Charle's age is 8 years older than five times Mark's age.
• Charle's age is 63 years

To find:

• Mark's age

Solution:

Let us assume Mark's age as '5x'.

According to the question, we can observe that the difference between Charle's age and Mark's age is 8.

$\implies{\rm}$ Charle's age - Mark's age = 8

$\implies{\rm}$ 63 - 5x = 8

$\implies{\rm}$ -5x = 8 - 63

$\implies{\rm}$ -5x = -55

$\implies{\rm}$ x = 11

Final Answer:

Therefore, Mark's age is 11.
