Question

69. In the examination 45% students failed and
550 students passed. What was the total
number of students who appeared in the
examination?​

Answer 1

Step-by-step explanation:

percentage of failed students = 45%

remaining percentage of passed students = 55%

=> 55% = 550/x *100. ( X = number of students who appeared)

=> X = 55000/55

=> X = 1000.
