I just added 49 to 11 and got 60.

$65*3$ -60=135

I now I have to divide by 2, so I checked for the numbers that ended with .5 and got the answer.

The answer can be found by just checking the answers. Just adding 49 to the smaller weight and seeing if it equals the bigger weight will give you the answer. While this is a good problem, the answer needs to be better hidden.

Let Golden Retriever = $g$ , Boxer = $b$ , Chihuahua = $c$

$\frac{g + b + c}{3}$ = 65

$\frac{49 + 2b + 11}{3}$ = 65

$\frac{60 + 2b}{3}$ = 65

$60+2b$ = 195

$2b$ = 135

Therefore $b$ = 67.5

And by following the equation ,

Boxer = 67.5 , Golden Retriever = 116.5 , Chihuahua = 11
