Question

Today 25% of the student are absent in the class and au are present. How many students are on the roll?

​

Answer 1

Step-by-step explanation:

Percentage of students absent =25

Number of students present =45

We know that total strength of students is equal to 25% absent+45 present =100%

So percentage of students present=100–25=75

Therefore total strength =45×100/75 =60.

Let me varify my answer,

25% absent=60×25/100 =15

Number of students present=45

Therefore total strength =15+45 =60.
