If 50% of 100 is greater than 20% of a number by 47, what is the number?

If 50% of 100 is greater than 20% of a number by 47, what is the number?

Answer/Solution

15

Steps/Work

Explanation:
50/100 * 100 - 20/100 * x = 47
50 - 20/100 * x = 47
3 = 20/100 * x
3 * 100 / 20 = x
15 = x

Step by Step Solution

In order to solve problem, you must evaluate (n₁ * n₀ / 100 - n₃) / (n₂ / 100).

n₀ =	50
n₁ =	100
n₂ =	20
n₃ =	47

(n₁ * n₀ / 100 - n₃) / (n₂ / 100)
Evaluate n₀ / 100 = 0.5
(n₁ * 0.5 - n₃) / (n₂ / 100)
Evaluate n₁ * 0.5 = 50
(50 - n₃) / (n₂ / 100)
Evaluate 50 - n₃ = 3
3 / (n₂ / 100)
Evaluate n₂ / 100 = 0.2
3 / 0.2
Evaluate 3 / 0.2 = 15
15
The answer to the problem and the result of (n₁ * n₀ / 100 - n₃) / (n₂ / 100) is 15
