Step 1

**Given:**

Mass of the student = 75 kg

Height of one stair = 0.15 m

Number of stairs = 80

Time taken to climb the 80 stairs = 65 s

1 g fat burns and gives energy = 9 kcal

1 kcal = 4186 J

Step 2

(A) Calculating the number of times, the student must climb the stairs in order to lose 1 kg:

Step 3

(B) Calculating the aver...
