if 3 men or 6 boys can finish a work in 20 days how long will 4 men and 12 boys take to finish the same work ?​

Answer 1

Answer:

three men can do the job in 20 days 6 boys can do in 20 days so we now I need to find how much days can I one boy and one man can do the work in 51 when do the job in 3 into 20 equal to 60 days 1 boy can do the job work in 20 days 14 boys 6.1.3 is equal to reduce the fraction 1.23 man is equal to 3 upon 60 is equal to reduce the fraction 1.20 now we can do the same process with the men and 12 boys boys 12 120 reduce the fraction 1.10 man 4.65 the fraction word 150 now I need to see the number of days this can complete the work in so what happened 15 + 1 upon 10 is equal to change to is upon 30 + 3 upon 30 is equal to 5 upon 30 reduce fraction is equal to 1 upon 6
