Answer:
The required number is [tex]82[/tex].
Step-by-step explanation:
Given: I thought of a two-digit number. The unit digit of my number is a prime number and the tens digit is four times as big as the unit digit.
Let the unit digit of number be [tex]x[/tex].
And tens digit of number is [tex]4x[/tex].
As we know that,
Prime numbers are whole numbers greater than 1, that have only two factors 1 and the number itself.
Eg: [tex]2,3,5,7,...........[/tex]
Now, as per question
unit digit can be only [tex]2[/tex] and tens digit will be [tex]8[/tex] because only this pair of number satisfies the condition for two-digit number.
Therefore, the required number is [tex]82[/tex].
Hence, my number is [tex]82[/tex].
