Answer:

Let the two digit number be 10x + y

Given that the sum of the digits is 9

x + y = 9 (equation 1)

Given that the number obtained by interchanging the digits exceeds the given number by 27

10y + x = 10x + y + 27

9x - 9y = - 27

taking 9 as common

x - y = - 3 (equation 2)

Adding equation 1 and 2

x + y = 9

x - y = - 3

2x = 6

x = 3

3 + y = 9

y = 6

The number is 10x + y is 36.

sanoj4: 9 common kaise hoga

aqibjawedkhan9p5p8sa: 9 common isliye lenge kyunki is side do 9 hai aur equal side ke us taraf 27 hai to wo 3 ban gaya
