Let unsuccessful candidate =x
then successful person =3x
total candidate =4x
According to Question now remaining
4x16 candidate.
now, unsuccessful candidate =x4
successful candidate =3x12
if we add 6 more unsuccessful candidate
x+2 unsuccessful candidate

2(x+2)=3x12
2x+4=3x12
x=16
total candidate=4x
4×16=64
so Ans =64
