Answer 1

Step-by-step explanation:

Given  

Three Students secured the first second and third positions in a mathematics quiz the average score of first 22 students is 30 the average score

Let the first second and third student represent x, y and z.

So average score of first and second will be x + y / 2

                                                      So x + y / 2 = 30

                                          Or x + y = 60

Also average score of all 3 students is  x + y + z /3

                            So x + y + z / 3 = 28

                             Or x + y + z = 84

                           Now 60 + z = 84

                        So z = 84 – 60

                       So z = 24

So the score of student who secured third position will be 24
