Question

in final exam of class 9 there are 50 students 10% students are failed . how many students passed in the exam​

Answer 1

Answer:

The answer is quite simple

It is 45 students passed

Explanation:

In a class there are 50 students

Let the failed students be 'x' Then passed students will be 50-x {eq-1}

Then x=50×10/100 (As 10% failed are given in question itself so 10/100)

x=5

So, we got the value of x

Now substitute x value in eq-1

we get 50 -5=45

So 45 students passed in the final exam
