विकल्प

• Hebrew the only foreign language which all three of Akhtar, Balram and Chintu took

• French is the only foreign language in which both Balram and Ehsaan took

• The number of friends who took in each language is unique

• None of the above

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 inall 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	✓	✓

The common language among Akhtar, Balram, and Chintu are Hebrew and Russian. Hence, Hebrew the only foreign language which all three of Akhtar, Balram and Chintu took is not true. The common language among Balram and Ehsaan areFrench and German. Hence, French is the only foreign language in which both Balram and Ehsaan took is not true. Hebrew and German have both three participants each. So The number of friends who took in each language is unique is also not true.
So, None of the above is the correct option
