Re: Interview Question (your Sunday ruined part 3)

Answer: Frog+Sheep+Horse=27

Work: (which took a whole bunch less time than typing it) Eq1 F+S = 10 thus F=10-S Eq2 F+H = 20 so F+H = 2(F+S) = 2F+2S so F+H-F=2F+2S-F thus H=F+2S

S+H = 24 so S+F+2S=24 thus F+3S=24 from Eq1 F=10-S so 10-S+3S=24 so 10+2S=24 so 2S=14 thus S=7 since S=7 then from Eq1 F=10-S thus F=3 From Eq2 F+H =20 so 3+H = 20 thus H=17 So F+S+H = howinthehelldoyougetthemallonthescaleatthesametime? Ed

The sheep gets hungry while you are doing the math and eats the frog, but that doesn't change the weight.

Of course one can't clean the platform until all the measurements are made.
