Question

the sum of two digits no is 15. if the number formed by reversing the digits is less than the original number by 27 number find the original number​

Answer 1

Let AB be the 2-digit number.

∴A + B = 15......(1)

The number formed by reversing the digits is BA.

∴AB = BA + 27

⇒10A + B = 10B + A + 27

⇒9A - 9B = 29

⇒A - B = 3........(2)

On solving equations (1) and (2), we get

A = 9 and B = 6.

Thus, the original number is = AB = 96

Hope you get it.
