A and B complete a work in 17 days. If A alone can do it in 34 days then, B alone can do
in______________(days).
Correct Answer:
C. 34
Explanation:
Given that A and B together can finish the task in 17 days, their collective work rate is 1/17 per day. Since A's solo work rate is 1/34 per day, B's rate is calculated by subtracting A's rate from the total (1/17 - 1/34 = 1/34). Thus, B would take 34 days to complete the work alone.
