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

Also called "H-bomb" or "fusion bomb", the hydrogen bomb is the most powerful explosive invented by man. Its force can reach 50 times that of an atomic bomb like those that were dropped on Japan and the reaction is the same that occurs spontaneously inside stars like the sun.
In contrast to what happens in nuclear fission, when heavy uranium atoms "break" releasing large amounts of energy, in nuclear fusion the hydrogen atoms (deuterium and tritium) come together to release energy.
The difference is that while nuclear fission releases about 10% of the energy contained in the nucleus of atoms, fusion can release about 40% of that energy.
