1. Faruk can complete a task in 20 days. He gets 2 assistants- each of whome can work as fast as he does. If all of them work together for 5 days, what percentage of the task will be complete?
- A. 40%
- B. 40%
- C. 40%
- D. 40%
Answer: Option B
Explanation:
This can be done easily by the following way.
যেহেতু ফারুকের দুই. Assistant তার সমান কাজ করবে ( 1/2 each), so total কাজ করতে তিনজনের মোট 20/2 = 10 দিন লাগবে।
So 5 days এ 50% কাজ হবে।
