Step-by-step reasoning process: The electronics store sold 327 televisions this Black Friday and might sell 50 more televisions the next year, for a total of 327 + 50 = 377 televisions. The second year they might sell 377 + 50 = 427 televisions. The third year, if they continue to sell 50 more televisions than they did the previous year, they will sell 427 + 50 televisions = 477 televisions on the Black Friday three years from now.
The question and answer:
Question and answer: On Black Friday a popular electronics store sells 327 televisions. This is 50 more than they sold last Black Friday. If this sales trend continues and they sell 50 more televisions each year for three years, how many televisions will they sell on Black Friday three years from now?
The answer is 477

Step-by-step reasoning process: Out of the 40, 40 x 1 / 10 = 4 students are absent. So, 40 - 4 = 36 students are present in school. Out of the 36, 36 x 3 / 4 = 27 students are in the classroom. This means, 36 - 27 = 9 students are in the canteen.
The question and answer:
Question and answer:
There are 40 students in a class. If 1/10 are absent, 3/4 of the students who are present are in the classroom, and the rest are in the canteen, how many students are in the canteen?
The answer is 9
