QUESTION

My age this year is a multiple of 5, by next year it will be a multiple of 7. How old am I?

EXPLANATION

The multiples of 7

  • 7 , 14 , 21 , 28 , 35 , 42 ,...

The multiples of 5

  • 5 , 10 , 15 , 20 , 25 , 30 , 35,...

Focusing on the multiples of 5 and when added to 1 , the sum is present on the multiples of 7.

Now, I noticed that 20 is the possible answer.

Because when 20 is added by 1 or increased by 1 , the sum will become a multiple of 7.

ANSWER

  • 20 years old
