Once Ajay went to the office of ROCK LINE COURIER with 4 different envelopes. The clerk in the office measured the weights in all possible pairs. The weights obtained are 59gm, 61gm, 62gm, 63gm, 64gm and 66gm. What is the weight of the heaviest envelope?
Can anyone solve it?

Acccording to me,
Given condition : x > 65 & amp; x < 72(according to Arun opinion).
x > 60 & x < 70(according to Arun's brother).
x < = 68(according to Arun's mother).
So, average age = 65 + 72 + 60 + 70 + 68/5.
335/7 = 67.
Ans is 67.
