Answer»

Answer:

17.

Step-by-step explanation:

Let the numbers are a and 3A( both are +ve, so we can say the 3a > a ).

When 17 is added to both:

             New numbers are a + 17 and 3a + 17.

Given,

      if 17 is added the both the numbers then ONE of the new number becomes twice.

   Greater number = 2 x smaller one

 ⇒ 3a + 17 = 2( a + 17 )

 ⇒ 3a + 17 = 2A + 34

 ⇒ 3a - 2a = 34 - 17

 ⇒ a = 17

       Hence the required number is 17.
