If P is a three digit number where first digit is three times the last digit and no digit is repeated. How many P are possible which are divisible by 6?
A number consists of four different digits where last digit is two times the first digit, second digit is two times the last digit and third digit at tens place is 3 less than the second digit. What is the difference of this four digit number and number formed by reversing its digit?
Can you find a five digit number which has no zeros no digit is repeated, where:
The first digit is a prime number. The second digit is the fifth digit minus the first digit. The third digit is twice the first digit. The fourth digit is the third digit plus three. The fifth digit is the difference between the first digit and the fourth digit.
What is the five-digit number, no zeroes, in which the second digit is three times the first, the third is one more than the second, the fourth is four times the first, and the last is one-half more than the second?
The sum of all digits of a 5 digit number is equal to the number of two digit formed by using the ten thousands and hundreds place digit in order. If five digit number has 1, 2 , 3 & 4 and no digit is repeated in the number, then What are the total number of possible number?
