u can easily gt the total number of people by multiplyin 7 by six because 7 is the mean and it is calculated by addin ol thn dividin by six wich gives yu 7.
thn deyre sayin tht the mode is 8 so 1 of the three numbers is 8 again..and let the other two remain as they r for a while..
nw wen u find the median yu first put dem in an ascendin order..
so wat gives yu 7.5 wen divided by two? wich is 7..because 7+8 divide by two is 7.5 wich is the mean and i no dat ure smart enuf to find out the last 1..
