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
