In an examination, 40% of the students failed in Mathematics, 30% failed in English, and 10% failed in both subjects. If 144 students passed in both subjects, what is the total number of students who appeared for the examination?
A. 400
B. 360
C. 300
D. 480
Answer: Option B
Solution (By JKSSB Mock Tests)
Total failed percentage = Failed in Math + Failed in English - Failed in Both = 40% + 30% - 10% = 60%. Total passed = 100% - 60% = 40%. 40% of total students = 144. Total students = (144 * 100) / 40 = 360.
