Question : 83 of 120

Marks: +1, -0

In an examination, 78% of the total students who appeared were successful. If the total number of failures was 176 and 34% got first class, then how many students got first class?

Validate

Solution:

Let total no. of students be x
Successful = 78%
∴ Failed

= (100 - 78)% =22%

∴ 22% of x = 176

{22x}/100=176

X=800
Frist class

= 34% \;\of 800 = 34' 800/100=272
