Answer 1

Answer:

Sol. Number of students absent on a rainy day = 30% Percentage of students = 100 - 30= 70% Present students = 84

Total students =

$\frac{84 \times 100}{70}$

= 120

Answer 2

$\sf \pink \bigstar \: Question :$

On a rainy day, 30% the students of a class were absent. if 84 students were present, what was the strength of the class?

$\sf\red \bigstar \: To \: Find:$

•We need to find the strength of the class.

☆Solution:

$\orange \maltese\sf \: no.of \: children \: present = 84$

$\green \maltese \sf \: no. \: of \: children \: absent = 30\%$

$\tt100\% - 30\% = 70\%$

So 70% students were present.

We have to multiply 84 and 100 and divide it by 70.

$\bigstar \frac{84 \times 100}{70} \implies120$

♪ So the total strength is 120 students.
