Question

Write all the 2-digit numbers which is added to 27 get reversed

Answer 1

Step-by-step explanation:

Let nos be 10X + Y, so the number is written as XY

for example, If it is 25, it is 10×2 + 5.

so our equation formed is

10X + Y + 27 = 10Y + X

9X + 27 = 9Y

X + 3 = Y

now the upper limit for a digit of a number is 9.

Y------X

9 6

8 5

7 4

6 3

5 2

4 1

We cant take X = 0 because if we did it wont be a 2 digit number.

So the numbers are

14

25

36

47

58

69
