if the digits are A and B, then we are given:
A + B = 6
A * B = (10A + B) / 3
∴ B = 6 - A
∴ A * (6 - A) = (10A + [6 - A]) / 3
∴ 6A - A2 = (9A + 6) / 3
∴ 6A - A2 = 3A + 2
∴ 6A - A2 - 3A - 2 = 0
∴ A2 - 3A + 2 = 0
∴(A - 2)(A - 1) = 0
∴A ∈ {1, 2}
A + B = 6
∴ B ∈ {5, 4}
∴ The numbers 15 or 24 both meet these conditions.
An International Article Number, also called an ean-13, has 13 digits. The original Universal Product Code has 12 digits. The barcode became a part of daily life with the supermarket.
Since the sum of the digits is divisible by 3, the original number is also divisible by 3.Since the sum of the digits is divisible by 3, the original number is also divisible by 3.Since the sum of the digits is divisible by 3, the original number is also divisible by 3.Since the sum of the digits is divisible by 3, the original number is also divisible by 3.
There are two numbers that satisfy the criteria. 38 and 83
whats the answer please??
It can have up to 5 digits.
52 is a number whose digits have a product of 10.

-- "The sum of a two-digit number" is unclear. I took it to mean"The sum of the digits of a two-digit number."-- "... the product ?" is unclear. Are you looking for the product of the two digits,or the product of the forward and backward numbers ?-- It's not possible to write a number whose two digits sum to 12 and whosereverse exceeds it by 25. The tens digit would have to be 4.611... and the unitsdigit would have to be 7.388... .Then(4.611...) + (7.388...) = 12(46.111...) + (7.388...) = 53.5(73.888...) + (4.611...) = 78.5Difference = 25So, the number can't be written, but ...The product of its two digits is 34.071 (rounded)The product of the forward and reverse numbers is 4,199.75 (rounded)

A) If a number has two digits, then the sum of its digits is less than the value of the original two-digit number.

Possibility of two digit no whose sum is 17 89 and 98 Reverse of 89 is 98. 98 is 9 less than the original no 89. 89 is original no
