On December 5 or 6 1492 a fateful wind led Christopher Columbus to the island of Haiti that he renamed Española
thinking that it looked like Spain. Guacanagaric, the cacique of the Marien in the northern part of the island, warmly welcomed
Columbus. He thought the Taino looked coward and could easily be defeated and enslaved:
"They...brought us parrots and balls of cotton and spears and many other things... They would make fine servants... With fifty
men we could subjugate them all and make them do whatever we want.
Explanation:
20 men can do 1 W in 36 days
=> 20 men can do 1/36 W in 1 day
=> 10 men can do 1/72 W in 1 day.
30 girls can do 1W in 36 days
=> 30 girls can do 1/36 W in 1 day
=> 12 girls can do 1/90 W in 1 day.
Together 10 men and 12 girls can do 1/72 + 1/90 W in 1 day
= 9/360 = 1/40 W in 1 day.
Therefore they need 40 days to do the piece of work.
