the list price of a watch costing $450 and $700 if it was sold at sucessive discounts of 10% and d% the net profit is $54 if instead of offering sucessive discounts a single discount of 1.5d% is offered the profit would be?

• The question should be like this "The list price of a watch costing $450 is $700."
  
  Solution:
  List Price = 450,SP = 700
  1st discount of 10% = 700*(100-10)/100 which is 630
  If 2nd discount is d% then the profit is $54, so the total net profit price is 450$+54$ = 504$
  i,e 630*(100-d)/100 = 504
  By solving we will get d = 20%
  Then in single discount 1.5d% i,e 1.5(20)% = 30%
  Total price after 30% discount is 700(100-30)/100 = 490$
  So total profit is 490-450 = 40$
