Question

Alberto, Oliva, Bailey, Sivan and Kenyatta are all friends. They all have dogs, and decided to see which dog weights the most. Below are clues to the dogs' weights. Use the clues to figure out how much each dog weights. Clue 1: Bruiser weighs 4 times as much Princess. Clue 2: Polo weighs 3 more pounds than Bailey's dog. Clue 3: Shadow's weight is 5 pounds more than Max's weight. Clue 4: Sivan's dog weighs 4 times as much as Polo. Clue 5: Max is 5 times heavier than Princess. Clue 6: Olivia's dog weighs 7 pounds more than Bruiser. Clue 7: Polo weighs 10 pounds. Directions: Match each owner and dog and the dog's weight.

Explanation / Answer

First jot down the info you have about dogs or people:

Brusier = 4( Princess)
Polo = 3+BaileyD
Shadow = 5+Max
SivanD =4(Polo)
Max = 5( Princess)
OliviaD = 7+Bruiser
Polo = 10

Then lets derive info from the existing info and the info in the question:

SivanD = 40 ( from the last and 5th Eqn)
BaileyD = 7 from the 2nd Eqn and the last

From the question we know for sure that Sivan owns Shadow, whose weight is 40
From the question we know for sure that Bailey owns Princess, whose weight is 7
Hence, Bruiser is 28( from 1st eqn) and its owner is Alberto
Max weights 35 pounds( from 2nd last eqn), and is owned by Olivia.
Kenyetta and polo thus are the person-dog pair, and Polo weighs 10 pounds.

SO, A = 3, B=4, C=1,D=5, E = 2
