Three blue chips are in a jar which is 10% of the entire chips. If 50% of the chips are white and the rest are green, how many green chips are there? Give the rationale and then the answer.
Let's think step by step. 10% + 50% = 60% of the chips in the jar are not green. So, 100% - 60% = 40% of the chips are green. There are 40% / 10% = 4 sets of 10% to make 40%. Hence, there are 3 chips x 4 sets = 12 green chips.. The answer is: 12.

It takes Jennifer 20 minutes to groom each of her 2 long hair dachshunds. If she grooms her dogs every day, how many hours does she spend grooming her dogs in 30 days? Give the rationale and then the answer.
Let's think step by step. She has 2 dogs and it takes 20 minutes to groom just 1 dog so it takes her 2 * 20 = 40 minutes per day to groom 2 dogs. In 30 days, she will have spent 30 * 40 = 1,200 minutes grooming her dogs. There are 60 minutes in an hour so she spends 1200 / 60 = 20 hours grooming her dogs.. The answer is: 20.

There are 14 chickens in the coop, and twice that many in the run. There is 4 less than double the number of chickens free ranging as in the run. How many chickens are free ranging? Give the rationale and then the answer.
Let's think step by step. Coop:14 chickens. Run:14(2) = 28 chickens. Free Range:28(2) - 4 = 52 chickens.. The answer is: 52.
