If the digits are reversed, the number is reduced by 27. Find the number
​

Answer 1

Answer: 41

Explanation:

Let the units digit be x.

The tens digit =5−x

Original number =10(5−x)+x=50−9x

If digits are reversed, number is reduced by 27.

50−9x−27=10x+5−x

23−9x=9x+5

18x=18

∴x=1

Tens place =5−1=4

Therefore, the number is 41.

Answer 2

14 is the answer

x+y=5

x= 5-y

10x+y-27 = 10y+x

10(5-y)+y-27=10y+x

50-10y+y=10y+x

simplify n u will get the answer after finding x and y
