When the price of oranges is lowered by 40%, 4 more oranges can be purchased for Rs 12 than can be purchased for the original price. How many oranges can be purchased for Rs 24 at the original price?

• Let the original Price be "P" and Original Consumption be "Q"
  Thus P*Q=12
  Now, after the change in price:
  New price is 0.6p and the new quantity is (Q+4)
  Now, 0.6P*(Q+4)=12
  Solving, we get P=2
  Thus, we could purchase 12 oranges for Rs.24

• 12 Oranges can be purchased for 24rs.
  
  40% of 12rs = 4.8rs
  So, In a New price, 4 oranges can be bought for Rs.4.8
  
  Therefore,
  New price of 1 orange= 4.8/4 = 1.2rs
  For 12rs, we can bought = 12/1.2 = 10 oranges
  
  So, at original price 12rupees, we can bought = 10-4 oranges = 6 Oranges
  Original price = 12/6 = 2rs per orange
  
  So, Orange can be purchased for for 24rs = 24/2 = 12 oranges.

• let an orange be x Rs.
  for 12 Rs we get y oranges. ie
  xy=12.......
  when 40% is reduced ie 2x/5 is reduced.
  so new cost of an orange is 3x/5.
  f0r 12 Rs we get (y + 4) oranges.
  (3x/5)(y+4)=12.............
  from above 2 equation we get x= 2. ie
  2 Rs for an orange.
  so we get 12 oranges for 24 Rs.
  answers is 12.
