Answer 1

Answer:

4 students received exactly 2 medals

Step-by-step explanation:

Total number of medals awarded = 35 + 15 + 18 = 68

Number of medals awarded to the 3 students who got all 3 medals = 3 × 3 = 9

Thus, the other (58 - 3) = 55 students received (68 - 9) = 59 medals.

Let the number of students who received 2 medals be x and those who received 1 medal be y.

Thus, x + y = 55 ; 2x + y = 59

Subtracting both equations,

x = 4

Thus, answer = 4
