Q: A mother buys a box of sweets. She kept 1/3 of the sweets and divided the rest between her 3 children. The eldest got 8 sweets while the youngest got half as many. If there are 27 pieces of sweets in the box, how many sweets did the second child gets?
A: 6
Step-by-step reasoning process: The mother kept 27 x 1 / 3 = 9 pieces of sweets. So there were 27 - 9 = 18 sweets that were divided between the 3 children. The youngest child got 8 / 2 = 4 sweets. So the eldest and the youngest got a total of 8 + 4 = 12 sweets. Therefore, the second child gets 18 - 12 = 6 sweets.


Q: There are 19 marbles in a bowl, 5 of which are yellow. The remainder are split into blue marbles and red marbles in the ratio 3:4 respectively. How many more red marbles than yellow marbles are there?
A: 3
Step-by-step reasoning process: 5 out of 19 marbles are yellow so the remainder which is 19 - 5 = 14 marbles are blue and red. 14 marbles are split into blue and red in the ratio 3:4 so each "share" is 14 / (3 + 4) = 2 marbles. There are 4 "shares" of red marbles which totals to 4 * 2 = 8 red marbles. There are 8 - 5 = 3 more red marbles than yellow marbles.


Q: On a tough week, Haji's mother sells goods worth $800, which is half the amount she sells on a good week. What's the total amount of money she makes if she has 5 good weeks and 3 tough weeks?
A: 10400
Step-by-step reasoning process: If on a tough week she sells half what she sells on a good week, then on a good week she sells 800 * 2 = 1600 dollars. If she had 5 good weeks, the amount is 5 * 1600 = 8000 dollars. During the 3 tough weeks, she sells 3 * 800 = 2400 dollars. The total amount she sold in both weeks is 2400 + 8000 = 10400 dollars.


Q: After tests in California, the total number of Coronavirus cases was recorded as 2000 positive cases on a particular day. The number of cases increased by 500 on the second day, with 50 recoveries. On the third day, the total number of new cases spiked to 1500 with 200 recoveries. What's the total number of positive cases after the third day?
A: 3750
Step-by-step reasoning process: When 500 new cases were recorded after the tests, the total number of positive cases increased to 2000 cases + 500 cases = 2500 cases. With 50 recoveries, the total number of cases reduced to 2500 cases - 50 cases = 2450 cases. On the third day, with 1500 new cases, the total number of cases became 2450 cases + 1500 cases = 3950 cases. If 200 people recovered from the virus, the total number of people with Coronavirus became 3950 cases - 200 cases = 3750 cases.
