Question

A a positive number is three times another number, if 17 is added the both the numbers then one then one of the new number becomes twice the another number new number what is the number

Answer 1

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.
