Question: Johnny wrote an essay with 150 words. Madeline wrote an essay that was double in length, and Timothy wrote an essay that had 30 words more than Madeline's. If one page contains 260 words, how many pages do Johnny, Madeline, and Timothy's essays fill?
Answer with step-by-step thinking: Madeline's essay was 150 x 2 = 300 words. Timothy's essay was 300 + 30 = 330 words. All together, they wrote 150 + 300 + 330 = 780 words. Their essays fill 780 / 260 = 3 pages.
So the answer is 3.


Question: Alice had 10 dozens of watermelons. She sold 40% of it yesterday and 1/4 of the remaining today, How many watermelons are left to be sold tomorrow?
Answer with step-by-step thinking: Ten dozens of watermelons are equal to 10 x 12 = 120 watermelons. Yesterday, Alice sold 120 x 40 / 100 = 48 watermelons. So, there are only 120 - 48 = 72 watermelons left for today. Today, Alice sold 72 x 1 / 4 = 18 watermelons. Hence, 72 - 18 = 54 watermelons are left to be sold tomorrow.
So the answer is 54.


Question: The largest animal to have ever lived on earth is the blue whale. The tongue of an adult blue whale can weigh 6000 pounds. If one ton is 2000 pounds, how many tons can the tongue of an adult blue whale weigh?
