Q: Monica way studying for an exam. She studied for 2 hours on Wednesday and three times as long on Thursday. On Friday Monica studied half of the time she studied on Thursday. During the weekend (two days) Monica studied as much again as Wednesday, Thursday and Friday combined. How much time did she spend studying in total during the five days?
A: On Thursday, Monica studied for 3 * 2 = 6 hours. On Friday, Monica studied half as much, so 6 / 2 = 3 hours. Till the weekend, Monica studied in total for 2 + 6 + 3 = 11 hours. That means, on the weekend Monica studied the same amount of time, so in total, she studied for 11 + 11 = 22 hours. The answer is 22.

Q: Pulsar, the shuffle-dancing bear, Polly, the pink prancing poodle, and Petra, the proud portly pachyderm, are entertainers at the Big Top Circus. In one show, Pulsar stands on his two back legs for a total of 10 minutes. Then, Polly stands on her back legs for three times as long as Pulsar. And then, finally, Petra stands of his back legs for one-sixth as long as Polly. What is the combined length of time, in minutes, that the three entertainers stand on their back legs?
A: Polly stands on her back legs for 3 * 10 = 30 minutes. Petra stands on his back legs for 30 / 6 = 5 minutes. In total, the three entertainers stand on their back legs for 10 + 30 + 5 = 45 minutes'. The answer is 45.

Q: There were 50 fish in a pond and 3 times as many tadpoles. If Curtis catches 7 fish and half the tadpoles develop into frogs, how many more tadpoles than fish are there in the pond now?
A:
There were 50 x 3 = 150 tadpoles. There are 50 - 7 = 43 fish left in the pond. There are 150 / 2 = 75 tadpoles left in the pond. There are 75 - 43 = 32 more tadpoles than fish in the pond now. The answer is 32.
