Option 3 : 83

The total number of students is = 144.

The number of boys and girls is 7 : 5

So, the number of girls are = 60 and boys = 84

Bikash who is a boy is standing only in front of 6 girls means

there are only 6 girls behind him so

Bikash ( 6 )

Mohana who is a girl is standing after them

Bikash ( 6 ) Mohana

Praveen standing ahead of 5 girls and before Mohana

Here Praveen is a girl as only 6 girls are standing behind Bikash.

Bikash Praveen ( 5 ) Mohana

Now boys left = 84 - 1 (Bikash) = 83

Hence, the correct answer is 83.
