Solved Examples on Percentage Calculator

Solved Example 1:
30 is what percentage of 50?
Solution:
We know that Percentage (%) = (Value/Total Value) × 100
Percentage = (30/50) × 100
= 3000/50
= 60%
Therefore, 30 is 60% of 50.

Solved Example 2:
What is 20% of 80?
Solution:
We know that Percentage (%) = (Value/Total value) ×100
Total value = 80; Percentage = 20%
Let value = a
Now, we substitute these values in the formula,
20 = (a/80) × 100
(20/100) × 80 = a
a = 1600/100
a = 16
Hence, 20% of 80 is 16.
