Classification of 100 students based on the marks obtained by them in Physics and Chemistry in an examination.

The number of students scoring less than 40% marks in aggregate is:

We have 40% of 50 = (40/100 * 50) = 20

Required number = Number of students scoring less than 20 marks in aggregate

= 100 - number of students scoring 20 and above marks in aggregate = 100 - 73 = 27.
