In Arun's opinion,his weigh is greater then 65 kg bu less than 72 g . His brother does not agree Arun and he thinks
that Arun's weight is greater than 60 kg bat less than 70 g. His mother's view is that his weight cannot be greater than 68 g..If all of them are correct in their estimation, what is the average of different probable weight of Arun ?
Let Arun's weight be `x` kg.
According to Arun, 65 < `x` < 72.
According to Arun's brother, 60 < `x` < 70
According to Arun's mother, `x` < 68
The values satisfying all the above conditions are 66 and 67.
`:.` Required average = `((66 + 67)/(2))` = `(133/2)` = 66.5 kg.
