Answer 2

Answer:

6561

Step-by-step explanation:

Given the sum of a number and its 5/9 is equal to 5/6 of 151.2.

Let the number be x. The sum of number is x + 5 / 9 x

    x + 5 / 9 x = 5 / 6 x 151.2

      9 x + 5 x / 9 = 756 / 6

          64 x / 9 = 126

          64 x = 126 x 9

            x = 81

 Now squaring 81 we get 81 x 81 = Rs 6561
