Job takes 60 mandays + 80 boy days or 52 mandays + 96 boydays.
Thus 8 man days = 16 boydays so 2 boydays = 1 manday.
This means that 7 mandays and 10 boydays is equivalent to 12 mandays.
The job requires 60 + 80/2 ie 100 mandays so it would require 8 and a third days.

To solve the problem, first determine the work done by 3 men and 6 boys in one day. If 3 men and 6 boys complete the work in 20 days, their combined work rate is 1/20 of the work per day. Let the work rate of one man be ( m ) and one boy be ( b ). Thus, ( 3m + 6b = \frac{1}{20} ). Now, for 6 men and 8 boys, the work rate is ( 6m + 8b ). To find how long they will take to complete the same work, calculate the ratio of the work rates. The new work rate simplifies to ( 2(3m + 4b) ). Using the previous equation, we can find that ( 3m + 6b ) is half of ( 3m + 4b ) since ( 3m + 6b = \frac{1}{20} ) implies ( 3m + 4b ) is also constant. Hence, the time taken by 6 men and 8 boys to complete the work is 12 days.
it may take 30 days time
6 boys and 15 girls can do a piece of work in 4 days while 12 boys 3 girls do the same work in 5 days. In how many days will 1 boy and 1 girl do the work seperately ?
About 10 days.
In one day 1 man does 1/200th of the work, In one day 1 boy does 1/300th of the work, so in one day 6 men and 11 boys do (6/200 + 11/300) of the work, ie (18 + 22)/600 or 1/15th so between them they take 15 days.
