On a stormy day only 40% of a class of 30 students was present. Find the number of present students.

$\huge\bold\color{aqua}{Solution:-}$

Total students in the class = 30

Number of students present = 40% of 30

So,

$\frac{40}{100} \times 30$

$\frac{4}{10} \times 30$

$4 \times 3$

$12$

12 students were present.

Answer 2

Answer:

let the no. of present students be x

x/30*100=40

x*100=40*30=1200

x=1200/100=12

so 12 students were present

Hope this helps
