Ratio of number of the students passed to the number of students failed in the state ‘S’ is:

A 3 : 4

B 4 : 1

C 2 : 3

D 1:4

E None of these

Solution

Correct Answer: Option B

⇒ Students passed in state ‘S’ = 80% of 200 =\(\frac{{80}}{{100}} \times 200\)

⇒ Students failed in state ‘S’ = 20% of 200 = \(\frac{{20}}{{100}} \times 200\)

∴ Required ratio = 80/20 = 4/1

⇒ Ratio = 4 : 1.
