Question

56. In a two-digit number, the tens digit is one more
than twice the units digit. The sum of the digits is
36 less than the number formed by reversing the
digits. Find the product of the digits.​

Answer 1

Step-by-step explanation:

Let the tens digit be x.

Hence, the units digit will be 2x

Number =10×(x)+(2x)=12x

When 36 is added to the number, the new number formed =12x+36

As the digits are reversed, we can also write the new number as 10×(2x)+x=21x

Hence,

12x+36=10×(2x)+x

⇒12x+36=21x

⇒21x−12x=36

⇒9x=36

⇒x=4

Hence, the original number =12x=12×4=48
