In the exam, 45% of students failed and 550 students were successful. The total number of students appeared in the exam were:
- 800
- 900
- 1000
- 1500
Explanation
Total Students = X
Fail Student = 45% of X
Pass Student= 550
X x 45% of X = 550
X value is one so 45% of x means .45 so we less one from .45
1 - .55 = 550
X = 550/.55
X = 55000/55
X =1000
