Question

In a list of weights of candidates appearing for police
selections, the weight of A is marked as 58 kg instead
of 46.4 kg. Find the percentage of correction required.
a) 30
b) 20
c) 24
d) None​

Answer 1

A weight marked as 58kg

actual weight is 46.4kg

so, subtract the actual weight from the marked weight I. e,

58 - 46.4 =11.6

to calculate the percentage error

11.6/58*100

=20.

Answer 2

Answer:

Step-by-step explanation:

Concept:

A value or ratio that may be stated as a fraction of $100$ is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by $100$. The proportion therefore refers to a component per hundred. Per $100$ is what the word percent means. The word "percent" % is used to symbolize it.

Percentage Formula:

We must divide the value by the entire value to find the percentage, and then multiply the resulting number by $100$.

$Percentage formula = (Value/Total value) * 100$

Percentage Formula

To determine the percentage, we have to divide the value by the total value and then multiply the resultant by 100.

Example: $2/5 * 100 = 0.4 * 100 = 40 per cent$

Given:

In a list of weights of candidates appearing for police selections

The weight of $A$ is marked as $58 kg$ instead of $46.4 kg$

Find:

To find the percentage of correction required.

Solution:

Given the weight of $A$ is marked as $58 kg$

Where as the actual weight is $46.4 kg$

So we have to subtract the marked weight from the actual weight then we will get

                    $58kg - 46.4kg = 11.6kg$

To calculate the  correction of percentage using percentage formula

$Percentage formula = (Value/Total value) * 100$

                                 $= 11.6 / 58 * 100$

                                 $= 0.2 * 100$

                                 $= 20$

Hence the percentage of correction required is $20$.
