Answer 1

Answer:

YES I KNOW THE ANSWER

Explanation:

Sum of the digits of a 2-digit number is 9. When the digits are reversed, it is found that the resulting number is greater then the original number by 27. Find the number.

Answer

Let one's digit = x

And, ten's digit = y

Therefore, number is 10y+x.

According to the question,

x+y=9       ....(1)

Also,

10y+x+27=10x+y

x−y=3        ......(2)

Solving equation 1 & 2, we get,

x=6 and y=3.

Hence, the original number is 10y+x=36.
