A two digits number is 3 times of the sum of its digits. If the digits are interchanged, then the number thus obtained is 9 less than 3 times of the original number. Find the number.

The sum of the two digits of a two digits' number is 9. if the digits are interchanged, then the number thus obtained is 27 more than the original number. Find the number.

A number consists of two digits.Sum of its digits is 15.If the place of digits are interchanged then the number so obtained is 9 less than the original number. Find the original number.

A two-digit number is seven times the sum of its digits. If each digit is increased by 2, the number thus obtained is 4 more than six times the sum of its digits. Find the number.

A two digit number is 4 times the sum of its digits and the unit digit is 3 more than the tens digit . the number is :

A number of two digits is 3 more than 4 times of the sum of its digits. If the positions of the digits of the number be interchanged , then the new number thus formed is 18 more than the original number. Determine the number.

If the digits of a two digits' number are interchanged, then the number thus obtained is (5)/(6) part of the original number and the difference of the digits is 1. Find the number.

The sum of the digits of a two - digit number is 7. If the digits are reversed, the new number increased by 3, equal 4 times the original number. Find the original number.

The digit in the tens place of a two-digit number is three times that in the units place. If the digits are reversed, the new number will be 36 less than the original number. Find the original number number. Check your solution.
