If two values are 20% and 60% of a third value, what percentage is the first value of the second value?

Question: If two values are 20% and 60% of a third value, what percentage is the first value of the second value?

Solution:
Let
The third value x
∴ First value (20x)/100 = x/5
∴ Second value (60x)/100 = 3x/5

Now,
(First Value/Second value) × 100
= (x/5) × (5/3x) × 100
= 33.33%
