Q. A trader marks his goods up by 50% and declares two successive discounts of 20% each. What is his overall gain?
Option
a) 10% gain
b) 4% gain
c) 4% loss
d) 10% loss
e) No loss No gain

• Ans C.
  
  Let's Assume initial amount is 100
  trader intially marks his goods up by 50% means cost will be 150
  
  Then two successive discounts of 20% each
  First discount=150-150x0.2 = 120
  Second one =120-120x0.2 = 96
  
  Hence loss by 4%

• If x is his cost price, then
  selling price = x*1.5*0.8*0.8 = 0.96x
  loss=0.04x
  
  % loss = 100*0.4x/x= 4% ... option C

• CP = Rs. 100 50% up means MP=150 first discount 20% of 150 =30 means 120 after first discnt aftr 2nd 24 = 96. he had a loss of 4%

• assume that the original cost price is 100.
  then, since he increases it by 50%,hence 50% of 100 is 50.
  hence the cost at which he is trying to sell the material is 150.
  now when he offers the 1st discount then, 20% of 150 is 30, reduce this from the cost at which he is trying to sell, it becomes 120.
  now again a discount of 20% is offered, then take 20%of the price 120, which is 24.
  hence reduce this amt. from 120 we get 96.
  now originally the cost price was 100, now hes selling it at 96.
  hence a loss of 4rs.
  now for loss%=( loss/cost price ) * 100
  (4/100)*100=4% loss.

• consider the cost of his good 100,
  up by 50%=150,
  20%discount=120(150-30),
  20% again=96(120-24)
  so 96means --> 4% Loss

• overall gain=x*(150/100)*(80/100)*(80/100)
  =x*(96/100)
  =4%loss

• 50% increase
  20% discount means --> (-20)%
  Solution
  50 + (-20) + (50 X (-20))/100 = 20 %
  Since there are 2 discounts of 20%
  20 + (-20) + (20 X (-20))/100 = - 4 %.
  Minus means loss, so 4 % loss

• by the formula m+n+((mn)/100)
  
  for loss/dis negative sign will be used
  Final ans= [c]4% loss

• Answer: C
  
  overall gain=x*(150/100)*(80/100)*(80/100)
  =x*(96/100)
  =4%loss
