Final answer:
To find Jaya's weight, subtract the weight of Kavitha from the mean weight and divide the remaining weight by 2. Jaya's weight is 0 kg.
Step-by-step explanation:
To find Jaya's weight, we need to subtract the weight of Kavitha and then divide the remaining weight by 2 since Satwika and Jaya have the same weight.
Jaya's weight = (Mean weight - Kavitha's weight) / 2 = (40 kg - 46 kg) / 2 = -6 kg / 2 = -3 kg.
Jaya's weight is -3 kg. However, since weight cannot be negative, we can conclude that Jaya's weight is 0 kg.
