Answer 2

Answer:

33

Step-by-step explanation:

Srinath is 7th from the left and Venkat is 12th from the right

Now . If they interchange their positions, Srinath becomes 22nd from the left.

So, Srinath is 22 from left and 12  from right.

So, he has 21 boys before him and 11 boys after him.

So, total number of boys = number of boys before him +Number of boys after him + Srinath

                                          = 21+11+1

                                          =33

Hence there are 33 boys .

So, Option 3 is correct.
