A number consists of 3 digits whose sum is 10. The middle digit is equal to the difference of the other two and the number will be increased by 99 if its digits are reversed. What is the square of the number?
I'm thinking of a number.
What is the number?
I am a three digit number. The product of the first and last digits is less than 49. The sum of the first two digits is less than 16. The difference of the first and last digits is greater than 0. The sum of the digits is greater than 6. The difference of the last two digits is equal to 2. The sum of the last two digits is equal to 6. The sum of the first and last digits is equal to 8.
When a two digit number is multiplied by sum of its digits, the product is 715 but when the reverse of a two digit number is multiplied by sum of its digits the product obtained is 99 less. What is the sum of the digits of a number?
