Question

In a class ,30percent of students got more than 60percent marks and 84 students got 60percent marks .If the no. of students who got less than 60 percent marks is one fourth of the students who got 60 percent marks,then find the total no. of students in the class.​

Answer 1

Answer:

Let the total no of students to be x.

A/Q- 30 percent got 60percent + Mark's and the students who got 60 percent are 84 and no of students who got less than 60 percent are 1/4×84 =21.

Now total no of students up to 60 percent or below are 84+21=105

A/Q x-105 =30%of x(more than 60 percent)

=> x-105=3x/10

=>x-3x/10 =105

=>7x/10 =105

=> 7x= 105×10

=>7x=1050

=> x= 1050/7

Therefore x= 150.
