29 is the answer for this question

Step-by-step explanation:

Because 2+27=29 is the correct answer

Answer 2

Answer:

36

Step-by-step explanation:

Let us assume, x is a tenth place digit and y is the unit place digit of a two-digit number.

Therefore, the two-digit number = 10x + y and the reversed number = 10y + x

Given:

y = 2x -----------1

Also given:

10x + y + 27 = 10y + x

9y - 9x = 27

y - x = 3

Substitute the value of y from equation 1 in equation 2

2x - x = 3

x = 3

Therefore y = 2x = 2 * 3 = 6

Therefore, the two-digit number = 10x + y = 10*3 + 6 = 36
