Bob is 2 years older than Carol and the reverse of Carol's age is 3 times Bob's age, which makes Bob's to be 17 years.

<h3>How can Bob's age be calculated?</h3>

Let <em>1</em><em>B </em>represent Bob's age and let <em>1</em><em>C </em>represent Carol's age, we can write the following equations;

  • 1B = 1C + 2

Reversing Carol's age gives;

  • C1 = 3 × 1B

The multiples of 3 that have the form X1 have 7 as the rightmost number.

Given that 1B is a teenager, we have;

When;

  • 1B = 17
  • 1C = 17 - 2 = 15

The reverse of Carol's age is therefore;

  • C1 = 51 = 3 × 17

Therefore, from the given description, Bob's age <em>1B</em><em> </em>= 17 years

  • Bob is 17 years old
