Question

24)
A number consists
whose sum
two digits whose sum is 10
. If 8 is Subtracted from the number, its
digits are reveresed. Find the numbers
​

Answer 1

let the no x and y

so

so x + y = 10

and x - y = 8

on adding the equations

we get

2x = 18x= 9

we put x in eq. 1

so 9+y = 10y = 1 ans

the no is 91 when it is reveresed the answer is 19.

hope you understand this
