Question

4 men or 6 womener complete a work in 12 days. In how many days will 10 men and 3 women complete the same work together?​

Answer 1

Step-by-step explanation:

4 men take 12 days to do a job. So each man does (1/48)th of the job in a day.

6 women take 12 days to do a job. So each man does (1/72)nd of the job in a day.

3 men do (3/48)th (or 1/16) of the job in a day.

4 women do (4/72)th (or 1/24) of the job in a day.

3 men and 4 women will do (1/16)+(1/24) = (3/48) + (2/48) = (5/48)th of the job in a day.

Hence 3 men and 4 women will complete the job in 48/5 = 9 and 3/5th of the next day.
