Question 465564: . Simple question but big one on average age.sth like a, b, c weighted separately 1st a, b, c ,then a& b, then b &c ,then c & a at last abc, the last weight was 167,then what will be the average weight of the 7 reading?

If a,b,c combined weigh 167, we can find the average weight of the seven readings. Note that we are trying to find
 + (b+c) + (c+a) + (a+b+c)}{7})
We can collect like terms in the numerator:
}{7} = \frac{4(167)}{7} \approx 95.43)
