Let's denote the number of boys as B and the number of girls as G.

From the problem, we know two things:

1) B + G = 45 (the total number of students is 45)

2) 100B + 50G = 3900 (the total amount of money distributed is Rs.39, but since we're dealing with paise, we need to convert it to 3900 paise)

Now we can solve these equations step by step.

First, let's express G from the first equation:

G = 45 - B

Now we can substitute G in the second equation:

100B + 50(45 - B) = 3900

Solving this equation gives:

100B + 2250 - 50B = 3900

50B = 3900 - 2250

50B = 1650

B = 1650 / 50

B = 33

Substitute B = 33 into the first equation:

33 + G = 45

G = 45 - 33

G = 12

So, there are 33 boys and 12 girls in the class. The correct answer is 33,12.
