Answer 2

Answer:

answer is 65

Step-by-step explanation:

let two digit no is AB,

Ab=10*A+1*b,

   =10A+B

if it is reversed ,

10A+B = 10B+A,

ATQ, new number is formed is 9 less then the original number,

(10A+B) = (10B+A)+9,

9A - 9B = 9,

A-B = 1

A+B = 11,

A-b+A+b = 1+11,

2A = 12

A = 6

b = 11 - 6 = 5

10A+B

10*6+5

60+5

=65
