Which two digit numbers when added to 27 get reversed?

Find the sum of all two digit numbers which when divided by 4, yields 1 as remainder.

If we subtract 4 from the digit at the units place of a two digit number and add 4 to the digit at the tens place then the resulting number is doubled. find the number.

The sum of two-digit number and the number obtained by reversing the digits is 66. If the digits of the number differ by 2, find the number. How amny such numbers are there?

One of the two digits of a two digit number is three times the other digit. If you interchange the digits of this two-digit number and add the resulting number to the original number, you get 88. What is the original number?
