Waqas's mother says that his weight cannot be greater than 78 kg. If all the three predictions are correct, what is the average of different probable weights of Waqas? (a) 75 (b) 80 (c) 78.5 (d) 76.5​

Answer 1

Answer:

answer is (c) : 76.5

Step-by-step explanation:

waqas says that weight is between 75kg and 85 kg

but her sister says that his weight is between 70kg and 80 kg

then the possible weight is between 75kg and 80 kg

and then his mother says that his weight can't be greater than 78 kg

so, the range is between 75 and 78 kg

and here the possible option is (c)
