There are 75 persons in a seminar hall 20 percent of them sitting on chair, 40 percent of the remaining sitting on long benches. How many persons do not possess any seats?
[ A ] 36
[ B ] 15
[ C ] 30
[ D ] 33
Answer : Option A
Explanation :
Total number of persons = 75
The persons who are sitting on the chair
= $20\over 100$ × 75 = 15
Remaining persons = 75 – 15 = 60
The persons who are sitting on the bench
= $40\over 100$ × 60 = 24
Persons do not posses any seats
= 60 – 24 = 36
