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.

With the removal of Indians from American territory, the white nation became stronger. Jackson was the first democratically elected president. He fought for the "common man" and against banks.
<h3><u>Was the Jacksonian era a democratic era?</u></h3>
Even though Andrew Jackson was only president from 1829 to 1837, his impact on American politics was felt both before and after his presidency. The period from approximately 1824 to 1840 has been referred to as the "Age of Jacksonian Democracy" and the "Era of the Common Man."
However, by modern standards, the United States was far from democratic. Women could not vote and were legally under the control of their husbands; free blacks were considered second-class citizens at best, if not completely disenfranchised; and slavery was expanding in the southern states.
Furthermore, the period saw the relocation of Native Americans west of the Mississippi River, as well as the concentration of wealth in fewer and fewer hands. However, changes occurred that broadened political participation and reform movements emerged to address inequalities in American society.
