Each piglet in a litter is fed exactly one-half pound of a mixture of oats and barley. The ratio of the amount of barley to that of oats varies from piglet to piglet, but each piglet is fed some of both grains. how many piglets are there in the litter?
1) Piglet A was fed exactly 1/4 of the oats today
2) Piglet A was fed exactly 1/6 of the barley today
Answer is E - Is this correct?
Comments:
* reference to Piglet "A" - question refers to "Piglet"
Otherwise ans = C
cause
1/4th = 4/10(.5) = .2
1/6th = 6/10(.5) = .3
Adds up to .5, which is the total quantity so only 1 piglet. Would that be correct?
