Question

Four out of 5 students passed the entrance exam. On the same trend, if 252 students got passing mark, how many students took the examination?

Answer 1

315 students

Explanation:

Based on the question, we can deduce:

`(4)/(5) = 80percent \: passing \: rate`

Next we can find out the total number of students who sat for the examination.

80% = 252

`1percent \: = (252)/(80) \\ 100 \: percent = (252)/(80) * 100 = 315 \: students`
