In Karthik's opinion, his weight is greater than 55 kg but less than 62 kg . His father does not agree with Karthik, and he thinks that Karthik's weight is greater than 50 kg but less than 60 kg . His sister's view is that his weight cannot be greater than 58 kg . If all are correct in their estimation, what is the average of the different possible weights of Karthik?

Solution & Step-by-step Explanation

Let W be Karthik's weight in kg (assumed to be integer values). * According to Karthik: 55 < W < 62 ⟹ W \in {56, 57, 58, 59, 60, 61} * According to his father: 50 < W < 60 ⟹ W \in {51, 52, 53, 54, 55, 56, 57, 58, 59} * According to his sister: W \leq 58 Taking the intersection of all three conditions: 55 < W \leq 58 The possible integer values for W are 56, 57, and 58 . The average of these possible weights is: Average = \frac{56 + 57 + 58}{3} = 57 kg
