Answer 1

Answer:

36

Step-by-step explanation:

Given By making the two digit number changing the position of 7 times the number is equal to 4 times the number formed. If the unit is the difference of digits and the number of tens, the number is 3.

Let the number with tens be 10 q and other number be p. So The equation will be 10 q + p. Changing the equation we get 10 p + q

Now given 7(10 q + p) = 4(10 p + q)

                70 q + 7 p = 40 p + 4 q

                70 q - 4 q = 40 p - 7 p

                  66 q = 33 p

               p = 66 q/33 = 2 q

                 p = 2 q

Given difference of numbers is 3, so

               p - q = 3

                p = 2 q

          2 q - q = 3

           q = 3  

Now p = 2(3) = 6

So p q = 63, interchanging the numbers we get 36
