Question

Sum of the digits of a two-digit number is 9. When we interchange the digits, it is found that the resulting new number is greater than the original number by 27. What is the two-digit number

The perimeter of a rectangular swimming pool is 154 m. Its length is 2 m more than twice its breadth. What are the length and the breadth of the pool?​​

Answer 1

Answer:

Answer1: The number whose sum of the digits is 9, and when we interchange the digits the new number is 27 greater than the earlier number, is 36. Condition 2: The number obtained by interchanging the digits is 27 greater than the earlier number

A2

So, Length=AB=CD=(2x+2) and Breadth=BC=AD=x. The breadth of the rectangular swimming pool = 25 m. m. Therefore, the length and breadth of the rectangular swimming pool is 52 m and 25 m respectively

Answer 2

❥︎Answer࿐

The number whose sum of the digits is 9, and when we interchange the digits the new number is 27 greater than the earlier number, is 36. Condition 2: The number obtained by interchanging the digits is 27 greater than the earlier number.

So, Length=AB=CD=(2x+2) and Breadth=BC=AD=x. The breadth of the rectangular swimming pool = 25 m. m. Therefore, the length and breadth of the rectangular swimming pool is 52 m and 25 m respectively.
