Answer:
5000 students
Step-by-step explanation:
Let total number of students appeared in the exams is x.
20% of x have failed in both maths and science.
Here,in maths 60% of students passed.
%ag of students failed in maths= 40%
%ag of students failed in math — % of students failed in both maths and science = students passed in science but failed in maths i.e. 40–20 = 20%.
Likewise as 70% of students passed science
So 30% failed in science.
And Students failed in science only but passed in maths= %ag of students failed in science- % of students failed in both maths and science.
i.e. 30–20= 10%.
Given 2500 number of students passed in both maths and science = 100–(students failed in both maths and science+ students failed only in maths and passed in science+ students failed only in science but passed in maths)%
= 100–(20+20+10)= 50% of students passed both.
50% of x = 2500
50x/100= 2500
=> x= 5000.
So total number of students appeared in exam is 5000 in number
