Correct Answer: 13


Solution : Given that 20% of 50 marks = 0.2 × 50 = 10 marks
The number of students scoring less than 20% marks in aggregate = The number of students scoring 0 and above marks in aggregate – The number of students scoring 10 and above marks in aggregate
= 100 – 87 = 13.
Hence, the correct answer is 13.
