Question

9 men can complete a job in 15 days if a man works thrice as fast as a woman find the number of days taken by 15 women to complete the job​

Answer 1

Step-by-step explanation:

9 men = 15days

1 men = 15*9 = 135 days

rate:

1 men = 3 women

so, 1 women = 135 *3 = 405 days..

so, 15 women = 405/15 = 27 days

Answer 2

The number of days taken by 15 women to complete the job

Solution:

Given that,

9 men can complete a job in 15 days

Then,

1 men can complete the job in $9 \times 15 = 135\ days$

Given that,

A man works thrice as fast as a woman

Therefore,

1 men = 3 women

Find in how many days, 1 women will complete the work

$1\ women = 135 \times 3 = 405\ days$

Find the number of days taken by 15 women to complete the job

$15\ women = \frac{405}{15} = 27$

Thus number of days taken by 15 women to complete the job is 27
