Question

in a class, 95%of the students are present and 2 students are absent. what is the strength of the class?​

Answer 1

Answer:

40

Step-by-step explanation:

Let the total strength be x

If 95% are present , 5% would be absent

therefore 5% of Total strength (x) = 2 (As mentioned in the problem)

Now Evaluate x from the equation 5*x/100=2

we have x=40

Now coming to the unitary method

5% of Total Strength = 2

1% of Total Strength = 2/5

100% of Total Strength =(2/5)*100 = 40
