Question

Gertrude is 3 times as old as Murray. The sum of their ages is 48. How old are Gertrude and Murray?

Answer 1

Gertrude is 36 and Murray is 12.

Explanation:

12 times 3 is 36, making Gertrude three times as old, and adding their ages 12 plus 36 does equal 48. So, therefore, this must be the correct answer to the equation.
