Question

2. The sum of the digits of a two digit number is 8 and the difference between
the number and that formed by reversing the digits is 18. Find the number.​

Answer 1

Step-by-step explanation:

Q.2)

Sol: Let the 1st digit of the number be x.

and the 2nd digit be y.

Therefore, A/Q

x+y=8-------------------------------------(1)

and, y-x=18------------------------------------(2)

By (1)+(2) we get,

x+y+y-x=8+18=>2y=26=>y=13

Therefore, y=13

Now,Putting the value of y in (2) we get,

13-x=18=>x=-5

Therefore, x=-5

Therefore the Required number is:-65
