Hello,
Consider the total number of student sto be X
Now we know that 75% students passed in Both English and Mathematics as given in the question.
------ This means 25% students failed in both the subjects.
Also it is given that total students who failed in both English and mathematics are 40.
When we form equation from the above data it can be represented as -
( 25/100 ) • X = 40
On solving -
X = 160
Hence, total number of students are 160.
