Question

In an examination,72% of the total examinees passed.If the number of failures is 392,find the total number of examinees.

Answer 1

Let the total no. of candidates = c
no of passed =72% of c = 72/100 x c = 72c/100
no of failed = 392
so equation formed
c - 392 = 72c/100
c - 72c/100 = 392
28c/100 = 392
28c = 392 x 100
28c = 39200
c = 39200/28
c = 1400
so total number of examinees are 1200.
