Consider a two-digit number where the ratio of the unit digit to the tens digit is 2:3. If the total of these digits equals 15, what is the product of the two digits of this number?
Let, unit’s digit and ten’s digit of number be 2x and 3x respectively. 2x + 3x = 15 5x = 15 x = 15/5 = 3 Therefore, required number = 96 So, products of digits = 9 × 6 = 54
