Hint: It is given that the total number of employees in that organisation is 3450 and 42 % of them were promoted. From this to find the number of employees who got promoted we need to find the value of 42% of the total number of employees. The value of x% of a number N can be given by the formula $\dfrac{x}{{100}}*N$.Using this formula we can find the value 42% of 3450.
Complete step-by-step answer:
Step 1 :
We are given that there are 3450 employees in an organisation
Let N be the number of employees in the organisation
Therefore , N = 3450
Step 2:
We are given that 42% of the total number got promoted .
In order to find the number of employees we need to find the value of 42% of the total number of employees
That is , 42% of N
The value of x% of a number N can be given by the formula $\dfrac{x}{{100}}*N$
Therefore now we can find the value of 42% of N by using the above formula
Number of employees promoted = 42% of N
$
= \dfrac{{42}}{{100}}*N \\
= \dfrac{{42}}{{100}}*3450 \\
= 0.42*3450 \\
= 1449 \\
$
Therefore , the number of employees promoted is 1449
The correct option is a.
Note:1. We can also calculate the number of employees not promoted by subtracting this value from the total number of employees.
2.That decimal fraction which has 100 as its denominator is known as Percentage. The numerator of such a fraction is known as Rate Per Cent.
3.The percent rate is calculated by dividing the new value by the original value and multiplying by 100%. The percentage value or new value is calculated by multiplying the original value by the percent rate and dividing by 100%.
