Problem 1 :
The sum of the digits of a two digit number is 12. The number obtained by interchanging the two digits exceeds the given number by 18. Find the number.
Problem 2 :
Seven times a two-digit number is equal to four times the number obtained by reversing the order of its digit. If the difference between the digits is 3, then find the number.
Problem 3 :
The sum of the digits of a two digit number is 9. Also, nine times this number is twice the number obtained by reversing the order of the digits. Find the number.
Problem 4 :
The sum of the digits of a two digit number is 9. If 27 is added to it, the digits of the numbers get reversed. Find the number.
Problem 5 :
The sum of a two-digit number and the number by reversing the digits is 66. If the digits of the number differ by 2, find the number. How many such numbers are there?
Problem 6 :
A two-digit number is 4 more than 6 times the sum of its digit. If 18 is subtracted from the number, the digits are reversed. Find the number.
1) the required number is 57.
2) 36
3) 18
4) the original number is 36.
5) Two digit numbers are 42 and 24.
