Question

the unit digit of a number is twice the tens digits . if 27 added to the original number the result will be the same as the number obtained when the digits are reversed . find the original number​

Answer 1

Answer: 36

Step-by-step explanation:

Let the number in the tens place be x

Then the number in the units place = 2x

Therefore, the number is 10x + 2x = 12x

By data,

12x + 27 = 20x + x

12x + 27 = 21x

27 = 9x

x=3

Hence, the number is 36
