Clearly, every member except one (i.e. the winner) must lose one game to decide the winner.

Thus, minimum number of matches to be played = 30 - 1 = 29.

Question: 4

Five children take part in a tournament. Each one has to play every other one. How many games must they play?

(A) 6

(B) 8

(D) 12

View Answer

Ans: C

Clearly, we will consider the following matches:

(i) matches of first player with other 4 players.

(ii) matches of second player with 3 players other than the first player.

(iii) matches of third player with 2 players other than the first and second players.

(iv) matches of fourth player with one player other than the first three players.

So, number of matches played during the tournament
= 4 + 3 + 2 + 1 = 10.

Question: 5

12 years old Manick is three times as old as his brother Rahul. How old will Manick be when he is twice as old as Rahul?

(A) 12 years

(B) 14 years

(D) 18 years

View Answer

Ans: C

Manick's present age = 12 years, Rahul's present age = 4 years.

Let Manick be twice as old as Rahul after x years from now.

Then, 12 + x = 2(4 + x)

⇒ 12 + x = 8 + 2x

⇒ x = 4.
