Question

a number consists of two digits whose sum is 8. If 8 is added to the number its digits are reversed. Find the number.​

Answer 1

Step-by-step explanation:

Let digits be x and y

Number = 10x+y

Reversed Number = 10y+x

As per ques.

x+y = 8 --- (i)

10x+y +18 = 10y+x

=> 9x-9y = -18

=> x-y = -2 ----(ii)

Adding (i) and (ii)

2x =6

x=3

so y =5

so number is 35
