Back to Exercise
A team can finish a job in 20 days. After 5 days two members fall ill and the team's speed drops by 20%. How many days in all does the job take?
- A 24 days
- B 25 days
- C 22 1/2 days
- D 23 3/4 days Correct
Correct Answer: Option D
5 days → 1/4 done; 3/4 left
New rate = 0.8/20 = 1/25 a day
Time = 3/4 × 25 = 18¾ days
Total = 23¾ days
Trap: 25 days applies the slowdown from day 1.
Answer: 23¾ days
