So, in March the store has sold twice as dogs as cats, i.e. D = 2C and C cats.

In April, the store has sold double the dogs of March, i.e. 2D = 4C and triple of cats as in March, 3C.

Now we know that the sum of all sold animals is 500 = 2C + C + 4C + 3C = 10C. Thus, C = 50 and thus the number of dogs sold in March is equal to 2C = 2*50 = 100. Answer B
