64 players seeded from seed 1 to seed 64 participated in a knockout tennis tournament, where player no 1 to player no 64. The tournament would be played into 6 rounds. In the first round the player with the highest seed 1 would play with the lowest seed 64 which is designated match no 1, similarly the player with the second highest seed would play with the second lowest seed player, which is designated match no 2 and so on.
In the second round, the winner of match no. 2 of the first round would play with the winner of the match no 31 of the first round and this match is designated match no 2 of the second round and so on. In the similarly pattern the subsequent rounds will be played.

Set 2

A kabaddi team of 7 players must be selected from five North zone players Sameer, Kunal, Mahesh, Rahul and Prem and 5 south zone players Raghu, Shyam, Mohan, amar and Ramu.
There must be at least three players each from North and south zones in the team.

1. If Sameer is selected, Prem cannot be selected.

3. If Shyam is selected then Ramu cannot be selected.

Who among the following must always be selected ?
a. Only Kunal and Mahesh
b. Only Kunal, Mahesh and Rahul.
c. Only Kunal, Mahesh, Rahul and Mohan.
d. Only kunal, Mahesh and Mohan.

In case of selection of Raghu, Amar and Ramu can’t be selected. If Shyam is selected then Ramu can’t be selected. Only Mohan is over there who can be selected in each case.
From (1) Sameer and Prem can’t be selected together.
Therefore Kunal,Mahesh, Rahul and Mohan must always be selected.
Hence option C.

Set 3

Aman (57 years old), told his friend Amar, “I have seen 15 leap years”. After hearing this, Amar redefined a leap year as follows. Every year which is multiple of 2 or 3 or both is considered as leap year. As per Amar’s definition of a leap year, if both, the year of Amar’s birth and present year become leap years.

How many leap year must aman have seen according to this definition ?
a. 37
b. 38
c. 39
d. 40

Solution :-

As per Amar’s defition, every year which is divided by 2 or 3 or both is a leap year.
Amar’s birth year and present year both are leap year according to Amar’s definition.
Suppose birth year is 1803 and present year is 1860.
Years which are divided by 3 [1803,1860] = 20.
Years which are divided by 2 [1803,1860] = 29.
Years which are divided by 2 & 3 both [1803,1860] = 10.
Total leap years = 20+29-10 = 39.
Hence C.
