A. 42 B. 66 C. 98 D. 112 E. 154 Let us assume the number of dogs, cats and bunnies to be 3x, 7x and 11x Total dogs and bunnies = 14x. And we are given that 14x = 196. Hence x = 14. Dogs = 3x = 3*14 = 42 (Option A)

A. 42 B. 66 C. 98 D. 112 E. 154 Ratio of dogs to bunnies = 3:11 Therefore dogs/(dogs + bunnies) = 3/(11+3) = 3/14 Therefore dogs/196 = 3/14 Therefore dogs = 196 * 3/14 = 42 ans =a

Hi shasadou, These types of ratio questions can be approached in a variety of ways, but this question includes some rather significant 'shortcuts' that you can take advantage of. First off, the information about the cats is absolutely irrelevant. The information that matters is the ratio of dogs to bunnies and the TOTAL number of dogs and bunnies in the shop. The ratio of dogs to bunnies is 3:11  that means that there are MORE than 3 times as many bunnies as dogs. For example 3 dogs and 11 bunnies = 14 total 6 dogs and 22 bunnies = 28 total 9 dogs and 33 bunnies = 42 total etc. Thus, whatever the total number of dogs and bunnies is, the number of dogs would be LESS than 1/4 of that total (see the above examples for proof). Here, the total number of dogs and bunnies is 196. Since the total number of dogs is LESS than 1/4 of 196, and the answer choices are rather 'spread out', you'll find that only one answer 'fits' that description... Final Answer: GMAT assassins aren't born, they're made, Rich

A. 42 B. 66 C. 98 D. 112 E. 154 We can create the following ratio: dogs to cats to bunnies = 3x : 7x : 11x Since the shop carries 196 dogs and bunnies total in stock, we ignore the cats and include only dogs and bunnies in our calculation: 3x + 11x = 196 14x = 196 x = 14 Thus, there are 3(14) = 42 dogs. Answer: A

A. 42 B. 66 C. 98 D. 112 E. 154 We are told the ratio of Dogs : Cats : Bunnies = 3 :7 : 11 also equal to 21 We are now told the total of 196 Dogs + Bunnies which means 3+11 =14 /21* X = 198 Solve for X to get the tota no of animals = 2x = 588 or X = 294 animals Dogs = 3/21* 294 = 42 ans choice A
