Can I do it like this?
[(3 * 8 * P) / 100] = 1/2[4000 (1 +10/100) ^2 - 4000].
[(3 * 8 * P) / 100] = 1/2[4000 (1 +10/100) ^2 - 4000].

400 * 2 + 40 = 840.
S.I = 420.
p = (100 * 420/3 * 8) = 1750.
S.I = 420.
p = (100 * 420/3 * 8) = 1750.

400*2+40=840.
S.I = 420
p = (100*420/3*8) = 1750.
S.I = 420
p = (100*420/3*8) = 1750.
