The marked price of a shirt and trousers are in the ratio 1:2. The shopkeeper gives 40% discount on the shirt. If the total discount in the set of the shirt and trousers is 30%, the discount offered on the trouser is:
A)25% B)20% C)30% D)15%

• shirt = Rs100
  trouser = Rs200
  40% Discount on shirt= Rs60
  30% discount on both = Rs210
  price of trouser to get total discount of 30% is 210-60= Rs150
  that means Rs 50 discount on shirt which is 25% of 200.

  Trousr= 200
  shirt=40%of100=40
  Shirt =100-40=60
  discount offered on both =30%
  100+200=300
  30%of 300=90
  Trouser=90-40=50
  Discount offered=50/200*100=25%

• Marked price of shirt and trouser be x and 2x
  0.4x discount on shirt
  let y be discount on trouser
  total discount on pair = 0.9x
  So, (x-0.4x)+(2x-y) = (3x-0.9x)
  2.6x-y = 2.1x
  y = 0.5x
  Discount on trouser is 0.5x on 2x which is 0.5x/2x *100 = 25%
