Answer:
I. cp = rs6250
II. mp = rs8125
Step-by-step explanation:
The marked price is ...
mp = cp(1 +30%) = 1.30cp
The selling price is ...
sp = mp(1 -20%) = 0.80mp
The gain is ...
profit = sp -cp = (0.80(1.30cp)) -cp = cp(0.80·1.30 -1) = 0.04cp
rs250 = 0.04cp . . . . . the gain is rs250
rs6250 = cp . . . . . . . . divide by 0.04
__
mp = 1.30cp = 1.30·(rs6250)
mp = rs8125

Hey!
So since we know that a number was doubled, and that x represents the unknown number, we can come up with the first part of the equation: 2x.
Since we also know that 4.4 was added, the equation now becomes 2x+4.4
With the end result of the whole thing being 67.9, the equation now because 2x+4.4=67.9
