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
