1.	It takes 6 workers a total of 10 hours to assemble a laptop, with each working at the same rate. If 6 workers start at 9 am, and one worker per hour is added beginning at 3 pm, at what time will the laptop be assembled?1. 5 pm2. 6 pm3. 7 pm4. 8 pm
Answer» Correct Answer - Option 2 : 6 pm Given: No of workers = 6 6 workers take = 10 hours Formula Used: Total work = Efficiency × Time Calculation: 6 workers complete some work in 10 hours. ⇒ Total work done in 6 hours = 6 × 10 = 60 From 9 am to 3 pm all 6 workers work together for 6 hours. ⇒ Amount of work done by 6 workers = 6 × 6 = 36 hours From 3 pm to 4 pm, ⇒ Total time = 7 hours From 4 pm to 5 pm ⇒ Total time = 8 hours From 5 pm to 6 pm ⇒ Total time = 9 hours Total amount of work done up to 6 pm = 36 + 7 + 8 + 9 = 60 ∴ The laptop will be assembled by 6 pm.

Answer» Correct Answer - Option 2 : 6 pm

Given:

No of workers = 6

6 workers take = 10 hours

Formula Used:

Total work = Efficiency × Time

Calculation:

6 workers complete some work in 10 hours.

⇒ Total work done in 6 hours = 6 × 10 = 60

From 9 am to 3 pm all 6 workers work together for 6 hours.

⇒ Amount of work done by 6 workers = 6 × 6 = 36 hours

From 3 pm to 4 pm,

⇒ Total time = 7 hours

From 4 pm to 5 pm

⇒ Total time = 8 hours

From 5 pm to 6 pm

⇒ Total time = 9 hours

Total amount of work done up to 6 pm = 36 + 7 + 8 + 9 = 60

∴ The laptop will be assembled by 6 pm.
