Four soldiers - P, Q, R and S need to croos a bridge. A maximum of two person can cross it at a time. It is night and they just
have one lamp. Persons that cross the bridge must carry the lamp to find the way. A pair must walk together at the speed of slower person. After crossing the bridge, the person having faster speed in the pair will return with lamp each time to acompany another person in the group. Finally, the lamp has to be returned at the original place and the person who returns the lamp has to cross the bridge again without lamp. To cross the bridge, the time taken by them is as follows: P:1 minutes, Q: 3 minutes, R:7 minutes and S:10 mimutes. What is the total minimum time required by all the soldiers to cross the bridge?
<em>The initial solution most people will think of is to use the fastest person as an usher to guide everyone across. How long would that take? 10 + 1 + 7 + 1 + 2 = 21 mins. Is that it? No. </em><u><em>That would make this question too simple even as a warm up question.</em></u>
<em>.</em><em> To reduce the amount of time, we should find a way for 10 and 7 to go together. If they cross together, then we need one of them to come back to get the others. That would not be ideal. How do we get around that? Maybe we can have 1 waiting on the other side to bring the torch back. . The fastest way to get 1 across and be back is to use 2 to usher 1 across. So let’s put all this together.</em>
<h3>"our fathers brought forth on this continent, a new nation, conceived in Liberty".</h3>
Explanation:
The excerpt "our fathers brought forth on this continent, a new nation, conceived in Liberty" from Gettysburg address shows how Lincoln choose words to connect his speech to the declaration of independence.
This line reminds us that during the declaration of the American independence, the founding fathers of the constitution chose to set up a country based on the values of freedom and equality. Lincoln connects this line to address that their aspirations would be honored with full devotion.

Since New Jersey was a small state, they believed that there should have been one house in congress. Each state would have the same number of representatives regardless of the population. When Roger Sherman created the great compromise he considered the thoughts from the New Jersey plan and created a senate where each state had an equal amount of senator representation.
A managed float is the exchange rate policy where the government would intervene to control or manipulate the currency to save it from an economic shock. It may take place in a situation where the value of currency could fluctuate with respect to other currencies. At this point of time a government or central bank took the task to act as a buffer system between fixed exchange rate and flexible exchange rate.
