Answer 1

Answer:

In a class, 60% of the total number of students are boys and there are 14 girls. How many students are there in the class?

Let the no. of students be X.

Boys = 60% of X .

So Boys = (60/100)*X.

So left 40% of students are girls and it is given they are 14.

So total students X= total boys + total girls.

X = (60/100)*X+14.

X - (60/100)*X = 14.

(40/100)*X = 14.

X = (14*100)/40.

X = 35.

So total there are 35 students.
