​

Answer 1

Answer:

Answer: It will take 8 days for the team to finish the job. Step-by-step explanation: 12 men working for 10 days complete a job means the job requires the input of 120 man-days.

Answer 2

Answer:

10/9 days.

Step-by-step explanation:

12 men = 15 women

Then, 1 men = 15/12 = 5/4 women.

Now,

7 men + 10 women = 5/4 women + 10 women.

=> 45/4 women.

A/Q,

Time taken by 5/4 women to finish the work=10days

So, Time taken by 1 woman to finish the work=10×5/4

=> 25/2 days.

Now,

Time taken by 45/4 women to finish the work = 25/2 × 4/45 = 10/9 days.

Hope it helps you.
