Which number do you need to choose to continue this pattern:2, 7, 14, 23, ?, 47
Correct Answer
B. 34
Explanation
The pattern in the given sequence is that each number is obtained by adding consecutive odd numbers to the previous number. Starting from 2, we add 1 (odd) to get 3, then add 3 (odd) to get 6, then add 5 (odd) to get 11, and so on. Therefore, to continue the pattern, we need to add 7 (odd) to the last number, which is 23. Adding 7 to 23 gives us 30, and adding 4 (odd) to 30 gives us 34. Hence, the number that needs to be chosen to continue the pattern is 34.

5 women or 8 girls can do a certain amount of work in 84 days. How many days do 10 women and 5 girls need to do the same amount of work?
Correct Answer
A. 32 days
Explanation
In this question, it is given that 5 women or 8 girls can complete a certain amount of work in 84 days. This means that the work done by 5 women is equivalent to the work done by 8 girls. To find out how many days it would take for 10 women and 5 girls to do the same amount of work, we can use the concept of work efficiency. Since 5 women can complete the work in 84 days, it means that the work efficiency of 5 women is 1/84 of the total work per day. Similarly, the work efficiency of 8 girls is also 1/84 of the total work per day. Therefore, the combined work efficiency of 10 women and 5 girls would be (10/84) + (5/84) = 15/84 = 5/28 of the total work per day. To complete the same amount of work, it would take 28/5 or 5.6 times the number of days it would take for 5 women or 8 girls. Hence, 5.6 * 84 = 470.4 days. Since we need to find a whole number of days, the closest option is 32 days.
