There is given a table of Mark distribution 35-48, 49-60, 61-75, 76-88, 89-100No. Of students: 11, 25, 21, 9, 5Solution : Given that 10 students score 61, then rest (21-10)=11 students scores range 62 to 75.Though 76 to 100 are more than 62, so we took the number of rest students. So, total number of students who score 62 or more is (11+9+5)=25.Our answer is 25.
