Answer 1

It is given that the number of foreign languages took by each friend is different. i.e., one friend took one foreign language, another took two foreign languages and so on. With the given information we can conclude that

	Mandarin	Hebrew	Russian	French	German
Akhtar					✓
Balram	✓		✓		✓
Chintu	✓		✓	✓
Dara	x		✓
Eshaan				✓	✓

The number of friends taking Russian should be more than that of any language and since only one of Chintu and Ehsaan took it, it must be four. As Akhtar and Balram have to take, Ehsaan cannot take{condition (ii)}. From (iii), Chintu does not take German. All the players took at least two foreign languages except Dara. Hence, Dara took only one foreign language and Balram took in all the five foreign languages and Akhtar does not took in French. From (v), Ehsaan do not take Hebrew. Hence, the final arrangement is as follows.

	Mandarin	Hebrew	Russian	French	German
Akhtar	X	✓	✓	X	✓
Balram	✓	✓	✓	✓	✓
Chintu	✓	✓	✓	✓	X
Dara	X	X	✓	X	X
Eshaan	X	X	X	✓	✓

Four took Russian.
