Asked by admin @ in Math viewed by 366 People

In an examination, 35% candidates failed in one subject and 42% failed in another while 15% failed in both the subjects. if 2500 candidates appeared at the examination, how many candidates passed in either subject but not in both?

Answered by admin @


 

This can be solved using Venn diagrams. 

35% failed in one subject and 42% in another. 15% failed in both. 

Below is the venn diagram representing the failures, in a sample of 100. 

____________ 
______|_________ 
20% | 15% | 27% | 
|_____ |________| 
| 
____________| 
Obviously, those failing in one of the subjects = 20 + 27 = 47% 

Total = 47% of 2500 = 1175.
