In this case Preeta read total of 300 pages in 6 days by reading 10 more pages than the previous day.
Pages she read in six days can be calculated in this case as:
On the first day she reads 25 pages on the second day she reads 35 (25 + 10) pages, on the third day she reads 45 (35+10) pages, similarly on the fourth day she reads 55 (45+10) pages, on the fifth day she reads 65 (55+10) pages and on the last i.e. sixth day she reads 75 (65+10) pages, making it a total of 300 pages in six days.
Procedure:
Let the no. of pages she reads on day 1 be x
Then for six days:
x + x+10 + x+20 + x+30 + x+40 + x+50 = 300
6x + 150 =300
6x = 150 (300-150)
x = 150÷6
x = 25

Explanation:
Feudalism was a social and political system. ... Under feudalism, the king owned all of the land in his kingdom. However, the king would give gifts of land (called fiefs) to the lords or nobles who fought for him. These people were called “vassals.” Vassals would allow peasants called serfs to live on parts of their land.At the very top of feudal society were the monarchs, or kings and queens. As you have learned, medieval monarchs were also feudal lords. They were expected to keep order and to provide protection for their vassals. ... They had to rely on their vassals, especially nobles, to provide enough knights and soldiers.
