Answer :
We are given that the mean weight of the three people is [tex]$68\text{ kg}$[/tex]. This means that the total weight of the three people is
[tex]$$
\text{Total weight} = 68 \times 3 = 204\text{ kg}.
$$[/tex]
Two of the people weigh [tex]$58\text{ kg}$[/tex] each, so their total weight is
[tex]$$
58 + 58 = 116\text{ kg}.
$$[/tex]
To find the weight of the third person, subtract the total weight of the two people from the overall total weight:
[tex]$$
\text{Third person's weight} = 204 - 116 = 88\text{ kg}.
$$[/tex]
Thus, the third person weighs [tex]$88\text{ kg}$[/tex].
[tex]$$
\text{Total weight} = 68 \times 3 = 204\text{ kg}.
