Answer:
24 years old
Step-by-step explanation:
Let Malvin's age be x.
-  x / 2
- x / 2 + 5 = 5x / 10  [ By taking the L.C.M.]
- ( 5x / 10 ) * ( 1 / 3 ) = 5x / 30   [ Multiply with the reciprocal of 3 ] 
-  ( 5x / 30 ) * 2 = 5x / 15
Now let's solve the equation,
5x / 15 = 8
        5x = 8 * 15
        5x = 120
          x = 120 / 5
          x = 24
Therefore, Malvin is 24 years old.

For proof of 3 divisibility, abc is a divisible by 3 if the sum of abc (a + b + c) is a multiple of 3.
<h3>
Integers divisible by 3</h3>
The proof for divisibility of 3 implies that an integer is divisible by 3 if the sum of the digits is a multiple of 3.
<h3>Proof for the divisibility</h3>
111 = 1 + 1 + 1 = 3  (the sum is multiple of 3 = 3 x 1)  (111/3 = 37)
222 = 2 + 2 + 2 = 6 (the sum is multiple of 3 = 3 x 2)  (222/3 = 74)
213 = 2 + 1 + 3 = 6 ( (the sum is multiple of 3 = 3 x 2)  (213/3 = 71)
27 = 2 + 7 = 9  (the sum is multiple of 3 = 3 x 3)  (27/3 = 9)
Thus, abc is a divisible by 3 if the sum of abc (a + b + c) is a multiple of 3.
