952000=P(e^3-8)
P=952000/12~79333..

I used the result when the interest is compounded at every moment, then A=Pe^rt
r=R/100 and t is time in years...

sir by your method i am getting answer for max(4) as 70.. and i had a doubt in your video to find max(3) why arent you distributing the remaining 60+10 to the area where there are 2,1,0 overlap? by distributing it to 3 overlap you are minimizing the max value na
