Question

What number is 20 % of \[50\] \[?\]

Answer 1

Hint: To find the percentage of the given number with respect to the other number we have to multiply the given number with the given percentage and hence divide the result by hundred as per definition or we can use the basic formula so that we could obtain the given result .

Complete step-by-step answer:
Percentage is a word which is the combination of a per cent that means for every hundred and percentage is a number that is expressed in fraction .The number which is written in fraction form whose denominator is \[100\] is called as a percentage and the numerator of that number is called as rate per cent.
The symbol \[%\] is used to show that a number is a percentage \[,\] and sometimes we may use the abbreviation like pc, pct .
To find a number as a percent with respect to other number the following formula is used \[:\]
 \[=[\dfrac{\text{the number to be expressed in percent}}{\text{second number in respect of which the percent required to obtain}}\times 100] %\]
In mathematics \[,\] percentage is a number or a ratio that can be expressed as a fraction of \[100\]
 By a certain percent \[,\] we mean that many hundredths
Hence \[,\] x percent \[=x%\] \[=\] \[\dfrac{x}{100}\]
That means percentage is a fraction having the denominator one hundred
To find the \[x%\] of the quantity y \[,\] we will write \[\dfrac{x}{100}\times y\]
Now according to the given question to find the 20 \[%\] of \[50\] \[,\] here percent \[(%)\] means out of hundred
 \[ =\dfrac{20}{100}\times 50 \]
By solving this we will get the value \[=10\]
So, the correct answer is “10”.

Note: The term percent originates from the latin word percentum , which means per \[100\] .A percentage is a dimensionless number , it has no unit of measurement . We can also solve this using a unitary method but it needs a lot of practice. Basically Percent becomes a part of our daily life ,whether you are shopping ,working, banking or sports you have used percentage.
