Question
The classification of 100 students based on the marks
obtained by them in English and Mathematics in an examination is given in the table below. Study the table and answer the question that follows. If at least 40% marks in Mathematics are required for pursuing higher studies in Mathematics, how many students will be eligible to pursue higher studies in Mathematics?ÂSolution
To pursue higher studies in Mathematics, students must have obtained at least 40% marks = 40% of 50 = 20 marks. Therefore, students who have scored 20 marks or more in Mathematics are eligible for higher studies. From the MATHEMATICS row in the table: 40 and above: 3 students 30 and above: 23 students 20 and above: 65 students The number of students eligible to pursue higher studies in Mathematics is 65.
