3 years earlier, their average age was 320/20 = 16 years. So now their average age is 16 + 3 = 19 years.
let the number of students be x. The sum of all their ages = 40x120 joinedtotal is x+120The sum of all their ages = 40x+ 120*32=40x + 3840average age now is 3640x+3840 / x+120 =3640x+3820 = 36(x+120)40x+3840 =36x + 432040x-36x= 4320-38404x= 480x= 120initially there were 120. 120 joined. so total isd 240 students

Create a data structure to store the details for each student: typedef struct student_t { char name[30]; unsigned age; unsigned mark; } student; Establish an array to store the student data: size_t max = 100; // replace 100 with the actual number of students student students[max]; Use a loop to enter the data: for (size_t i=0; i<max; ++i) { printf ("Student name: "); scanf ("%s", students[i].name); printf ("Student age: "); scanf ("%u", students[i].age); printf ("Student mark: "); scanf ("%u", students[i].mark); } Calculate and display the average mark: unsigned sum = 0; for (size_t i=0; i<max; ++i) sum += student[i].mark; printf ("Average mark: %d\n", sum / max_students);
