Question : 5 is what percent of 54? Or, What percent of 54 is equal to 5?
Correct Answer 9.26%
Solution & Explanation
Solution
Method (1)
Given number = 54
To find, 5 is what percent of 54?
This question can be written as also
What percent of 54 is equal to 5?
⇒ ?% of 54 = 5
Let ? = m
And the meaning of "of" in mathematics is "Multiplication".
∴ m% of 54 = 5
⇒ m% × 54 = 5
⇒ m/100 × 54 = 5
⇒ 54 m/100 = 5
After cross multiplication, we get
54 m = 5 × 100
After transposing 54 to RHS, we get
m = 5 × 100/54
⇒ m = 500/54
⇒ m = 9.26%
Thus, 9.26% of 54 = 5
Thus, Answer = 9.26%
Method (2) Shortcut Method
Shortcut Method to find a number is what percent of other
If we have to find
? % of a = b
Here, let ? = m
Thus, above expression can be written as
m% of a = b
⇒ m/100 × a = b
⇒ m × a/100 = b
After cross multiplication, we get
m × a = b × 100
⇒ m = b × 100/a
Thus, using this formula, we can find a number (a) is what (m) percent of b
In the question, we have to find what percent of 54 = 5
Here, we have ? = m
a = 54
And, b = 5
Thus, using formula
⇒ m = 5 × 100/54
= 5 × 100/54
= 500/54 = 9.26%
Thus, 9.26% of 54 = 5
Thus, 9.26% Answer
