Question

Type 1 worker can work three times type 2 worker.. 12 type 1 worker can complete a task in 10 days..in how many days 4 type 1 worker and 8 type 2 worker can complete a task?

Answer 1

Answer:

18

Step-by-step explanation:

Hi,

Given that 12 type 1 workers can complete a task in 10 days

=> 1 type 1 worker will complete entire task in 120 days

=> In 1 day, a type 1 worker does 1/120th of task

=> 1 type 2 worker will complete entire task in 360 days

=> In 1 day, a type 2 worker does 1/360 th of task

(Since type 1 work can work 3 times type 2 worker)

4 type 1 workers will do 4*1/120 = 1/30th in 1 day

8 type 2 worker will do 8*1/360 = 1/45th in 1 day

So, in 1 day 4 type 1 workers and 8 type 2 workers will do (1/30 + 1/45)

= 1/18 th of task.

Hence in 18 days, they will finish entire task.

Hope, it helped !
