All children in class 7 passed the math exam. Details of grades are given below. Grade Percent Number of children A 40 B 30 C 25 D 9 Complete the table.

Given, Grade Percent Number of children A 40 B 30 C 25 D 9 Here, the percentage of marks of the students of grade A , B and C are given. So, the percentage of marks of the students from grade D = 100 - 40 + 30 + 25 = 5 . Let us consider the total number of students be x . Now, according to question, 5 % of x = 9 ⇒ 5 100 × x = 9 ⇒ x = 9 × 100 5 ⇒ x = 180 So, the total number of students is 180 . Thus, number of students in grade A = 40 100 × 180 = 72 . Number of students in grade B = 30 100 × 180 = 54 . And, number of students in grade C = 25 100 × 180 = 45 .
