The average mark of the students of a class in a particular exam is 65. If 5 students whose average mark in that exam is 20 are excluded, the average mark of the remaining will be 90. Find the number of students who wrote the exam.
[ "35", "14", "25", "55" ]
B
Let the number of students who wrote the exam be x. Total marks of students = 75 x. Total marks of (x - 5) students = 90(x - 5) 65x - (5 * 20) = 90(x - 5) 350 = 25x => x = 14 ANSWER:A
