To solve the problem, we will calculate the work done by both the boy and the girl, and then we will calculate the power developed by each of them. ### Step-by-Step Solution: #### Step 1: Calculate the height climbed by both the boy and the girl. - Each step is 20 cm high, and there are 30 steps. - Height (h) = Number of steps × Height of each step = 30 steps × 20 cm = 600 cm = 6 m. ...
