Answer 1

Step-by-step explanation:

given,

the weights (in kgs) of 15 students= 31,35,27,29,32,43,37,41,34,28,36,44,45,42,30

the numbers replaced= 44kg to 46kg, 27 kg to 25 kg.

so, the numbers are (in increasing order)

25,28,29,30,31,32,34,35,36,37,41,42,43,45,46

cancel out the numbers from the ends and the number left over is 35.

therefore, 35 is the answer.
