A tailor completes 2 suits per day. During wedding season, demand triples. If he hires 2 assistants, each half as efficient, how many days to finish 30 suits?
Correct answer: C. 7.5
- A. 5
- B. 6
- C. 7.5
- D. 8
Explanation
The tailor alone completes 2 suits per day. With demand tripling, he needs to produce 6 suits per day. By hiring 2 assistants, each producing 1 suit per day, the total output becomes 4 suits per day: 2 (tailor) + 1 (assistant 1) + 1 (assistant 2). To meet the demand of 30 suits, they need 30 / 4 = 7.5 days. Typically, this would round up to 8 days to account for practical work completion. Therefore, the correct choice is 7.5, acknowledging the precise calculation of days required. Option 5 incorrectly assumes a different rate of production or demand.
