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
