Question

The sum of two digits of a
two-digit number is 11. If 63 is
added to the number, the digits
get reversed. Find the number.​

Answer 1

Answer:

29

Step-by-step explanation:

a,b be the two digits here

a+b = 11. (1)

and 10a+b be the number formed by them

10a + b + 63 = 10b + a

9a - 9b = -63

9b - 9a = 63

b - a = 7. (2)

Adding (1) and (2)

2b = 18

b = 9 so a will be 2

the number will be 10a + b = 29
