I am greater than 15 and less than 40. if you double me, I become a number that ends in 0. One-fifth of me is equal to 5. Who am I?



Answer :

The number is 25. This is because, 25 is greater than 15 and smaller than 40. It is also a number that ends in a 0 if doubled, which is 50. Also, one-fifth of 25 is equal to 5, because 5 times 5 is 25
