In Jeevan’s opinion, his weight is greater than 65 kg but less than 72 kg. His brother does not agree with Jeevan and he thinks that Jeevan’s weight is greater than 60 kg but less than 70 kg. His mother’s view is that his weight cannot be greater than 68 kg. If all of them are correct in their estimation, what is the average of different probable weights of Jeevan?
Let Jeevan’s weight be X kg.
According to Jeevan, 65 < X < 72.
According to Jeevan's brother, 60 < X < 70.
According to Jeevan's Mother, X <= 68
The Values satisfying all the above conditions are 66, 67 and 68 .
Required average = (66 + 67+68)/3 = 201/3 = 67 kg.
