Answer:

17

Step-by-step explanation:

Let the total number of correct sums = x.

Then the total number of incorrect sums =24 - x.

Given that he gets 3 marks for each correct answer and loses 2 marks for each incorrect sum. and he obtained 37 marks.

3x - (24 - x) * 2 = 37

3x - 48 + 2x = 37

5x - 48 = 37

5x = 37 + 48

5x = 85

x = 85/5

x = 17.

Therefore the number of correct sums = 17.

Hope this helps!
