The digits of a positive integer, having three digits, are in A.P. and their sum is 15. The number obtained by reversing the digits is 594 less than the original number. Find the number.

A number of two digits is 3 more than 4 times of the sum of its digits. The number, obtained by reversing the position of the two digits is 18 more than the initial number. Find the number.

The number of 10 digit numbers formed by using the digits 1&2 is

Express the following statements in the form of simultaneous linear equations : (iv) The tens' digit of a number of two digits is double of its unit's digit. The number, obtained by reversing the two digits of the number, is 27 less than the original number.

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.

(xvii) Express the following statements in the form of simultaneous linear equations : (b) The one's unit digit of a two-digit number is twice of it's ten's unit digit. The number obtained by reversing the digits of the number is 18 more than the original 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 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 a two digits' number is divided by the sum of digits, the quotient is 6 and the residue is 3. Again, if two digits are interchanged, then the new number thus obtained, is divided by the sum of the digits, the quotient is 4 and the residue is 9. Find the number.

find the number of positive number with three digits divisible dy 5 such that the digits in each number in each number are different
