Reasoning and answer: In the first 2 rounds, Brendan wins a total of 2 rounds * 6 matches per round = 12 matches. In the last round, Brendan wins half of the matches which is 4 matches / 2 = 2 matches. Throughout the competition, Brendan has therefore won 12 + 2 = 14 matches.
The answer: 14

The difference in width between where they're starting from and their destination is 80 - 50 = 30 yards. The width increases 2 yards every 10 m along the river so they would have to cover (30 / 2) * 10 = 150 meters. Traveling at the rate of 5m / s, he will spend 150 / 5 = 30 seconds.
The answer: 30
Reverse engineering the question: Rodney and Todd are rowing down a river that is 50 yards wide at one end. If the river's width increases from this end uniformly by 2 yards every 10 meters along, and they row along the river at a rate of 5 m/s, how long (in seconds) will it take them to get to the point where the river is 80 yards wide?


Reasoning and answer: After giving away 4 / 5 of the cupcakes, Anna has 60 / 5 = 12 cupcakes. After eating 3 cupcakes, Anna has 12 - 3 = 9 cupcakes.

Reverse engineering the question: Trevor buys three bouquets of carnations. The first included 9 carnations, and the second included 14 carnations. If the average number of carnations in the bouquets is 12, how many carnations were in the third bouquet?


Reasoning and answer: If 10 sales professionals each sell 10 cars per month, then they sell a combined 10 * 10 = 100 cars per month. If the store has 500 cars, then it will take the sales team 500 / 100 = 5 months to sell all of the cars.
The answer: 5

Reasoning and answer: Mike is using 40 blocks / 2 = 20 blocks of type B. He uses in total 40 blocks + 20 blocks = 60 blocks of type A and B. So he is going to use 150 blocks - 60 blocks = 90 blocks of other types.
The answer: 90
