Thanks for your questions. Your question was – The average weight of 26 dogs was found to be 12.5 kg. When 1 more dog was added to this group, the average weight of the dogs was found to be 500gm more than the previous average weight. Find out the weight of the new dog that is added to the group.
Solvation:
According to he question,
The average weight of 26 dogs = 12.5kg
∴ The total weight of 26 dogs = 26*12.5 = 325kg
When one more dog is added to this group the total number of dogs = 26+1 = 27.
The average weight of 27 dogs = 12.5kg+500gms = 13kg
∴ The total weight of 27 dogs = 27*13 = 351kg
∴ The weight of the new dog that is added to the group = 351 – 325 = 26kg.
