In an examination,40% students passed in Maths only,30% passed in Science only and 10% students failed in both the subjects. If 400 students passed in Science, find the total number of students by drawing a Venn diagram.

506.1

Step-by-step explanation:

The total number of students is 506.1 because 400 Plus 40% Plus 10% is what answer i got . But notice i said but - if im wrong you can always figure it out yourself

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

it is impossible.
