.the mp of an article is 30% above the cost price when it is sold at the discount percent of 20% there is gain of rs250. I. find the cp II. find the mp

9514 1404 393

  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

its kind of blurry. can you put a clearer pic?
