Reasoning and answer: Before his maize is stolen, the maize he stores at the end of 1 year is 12 * 1 = 12 tonnes of maize. Before his maize is stolen, the maize he stores at the end of 2 years is 12 * 2 = 24 tonnes of maize. After his maize is stolen, he is left with 24 - 5 = 19 tonnes of maize. After he receives the maize donation, he has 19 + 8 = 27 tonnes of maize.
The answer: 27

Let x be the number of games that Frankie won. Then the number of games Carla won would be 2 * x. And the sum of all the games would be x + 2 * x = 30 games. Thus, the expression simplifies to 3 * x = 30. And the value of x = 10 games. Therefore, the number of Carla's wins would be 2x = 20 games.
The answer: 20
Reverse engineering the question: Frankie and Carla played 30 games of ping pong against each other. Frankie won half as many games as did Carla. How many games did Carla win?
Reasoning and answer: The percentage for women is 100% - 70% = 30%. Since 180 represents 30%, then 180 / 30 = 6 students represent 1%. Hence, 6 x 70 = 420 students are men.
The answer: 420
