Question

If you start with Malvin’s age, take half of it, increase that result by 5, then divide by 3, and finally double that, you get 8. How old is Malvin?

Answer 1

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.
