 A 2 B 20 C 11 D None of these
Question 5 Explanation:
→ There are 10 pair of shoes available in the dark room which means 20 individual shoes are available in the room.
→ If you pick shoes from one to ten individual shoes, there may be chance of getting same individual shoes.
→ There is no guarantee that getting one proper pair from 10 individual shoes.
