What is the ratio of number of seats that remained vacant in all the Non-AC classes on Wednesday and Thursday taken together to number of seats remained vacant in AC classes on Monday, Tuesday and Friday?

Show answer & explanation

Correct answer: C

Explanation

The correct answer is option 3 i.e. 62 : 39

The number of seats that remained vacant in all the Non-AC classes on Wednesday and Thursday taken together = 70 + 110  + 110 + 20 = 310 

The number of seats remained vacant in AC classes on Monday, Tuesday and Friday = 35 + 100 + 60 = 195

Required ratio = 310 : 195 = 62 : 39.
