answer is option E
We need to find the average age of 12 people in jury
statement 1
oldest and youngest age is 61 and 29
which is not sufficient as we are not sure about the age of ther 10 people
statement 2
average age of youngest 10 jury is 40
we are not sure about the age of the other 2 hence it is also not sufficient
if both the statement are combined
we will know the age of 11 people but the age of other people is not known hence it is not sufficient
so answer is option E
