Answer 2

Answer:

x = 150

step by step explanation:

let the total no. of students to be x.

A/Q - 30 percent got 60 percent +Marks and 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 percent of x(more than 60 percent)

=> x-105 = 3x/10

=> x-3x/10 = 105

=> 7x/10 = 105

=> 7x = 1050

=> x = 150
