Answer 1

two digit no is 22 snd when they added the ans is 4

Answer 2

The number is 84

Step-by-step explanation:

Let the two digit number be xy.

The multiples of 4 are 4, 8, 12, 16, 20, ...

First digit = Second multiple of 4

⇒ x = 8

Sum of the two digits = Third multiple of 4

⇒ x + y = 12

Substitute x = 8 in the above expression.

⇒ 8 + y = 12

⇒ y = 12 - 8

⇒ y = 4

Hence the number is 84.
