While selling a watch, a shopkeeper gives a discount of 5%. If he gives a discount of 7%, he earns Rs. 15 less as profit. The marked price of the watch is:
(a) Rs. 697.50
(b) Rs. 712.50
(c) Rs. 787.50
(d) Rs. 750

• If he increases the discount by 2%, then his profit is 15 less. Let the marked price be X.
  
  .02x = 15
  
  x = 750 marked price
  
  To check your work:
  If the discount was 5%, he would sell it for 712.50
  If the discount was 7%, he would sell it for 697.50

• Let the marked price be Rs. x
  Then, (7% of x ) - 15 = 5% of x
  ⇒ 7x / 100 - 5x / 100 = 15
  ∴ x = 750

• case1:
  MP=x,discount==5%
  >x-5%of x=0.93x
  
  case2:
  mp=x
  discount=7%

• let the marked price be x
  7x/100-5x/100=15
  2x/100=15
  x/50=15
  x=50*15
  x=750

• Answer
  (x*95%) -(x*93%)=15
  x=750

• 1.SP=95*MP/100
  2.SP =93*MP/100
  
  95*MP/100-93*MP/100=15
  2MP=1500
  MP=750
