Question

In a class of 150 students, 50 students cleared aptitude test A, 40 students failed only in aptitude test B and 20 failed in the both. How many students in both the tests? *​

Answer 1

Answer:

The Number of Students who failed is 140

The Number of Students that Passed is 10

Step-by-step explanation:

Given,

The Total Number of Students in the Class : 150

No of Students that Passed Aptitude Test A : 50

No of Students that Failed Aptitude only in Test B : 40

No of Students that Failed Both : 20

We Know that Since 50 Students Passed Test A, Then the number of Students that Failed = 150-50 = 100

Since 20 Students Failed in Both Tests, Then the Total Number of Students that Failed in A Only = 100-20 = 80

Then the Total Number of Students that Failed = 80 + 20 + 40 = 140

The Total Number of Students that Passed will be, 150-140 = 10
