Question

How to find number of students when % is given and remaining 30 students are given.

Answer 1

Answer:

Let the total students be x

At first subtract the % from 100

then the % which comes is equal to 30.

Now solve

Step-by-step explanation:

I can make you understand with the help of a example-

suppose in a class 70% of the students are boys and the rest are girls.

so, let, the total students be x

(100-70)% = 30%

= 30 % of x = 30

=30/100 x = 30

=30x = 3000

= x = 3000/30

= x = 100
