A person bought a certain number of oranges for Rs 7. If the prices of each orange was Rs 2 less, he would have bought 4 more oranges for the same amount. Find the number of oranges he bought originally.

• I think data is incomplete.
  
  If x ix price of each orange and y is no of oranges bought in initial case, then
  
  (x-2)*(y+4)=xy
  2x-y=4
  
  here amount spent is given as xy=7 which seems incorrect.

• Let no. of oranges =x.
  SO total amount for oranges = 7x.
  He buys x+4 oranges for rs 5 whose total amount =7x.
  Therefore 5(x+4)=7x... ==> x=10.

• possible case can be
  if he bought 8 oranges @ Rs 6 for each orange with an amount of Rs 48 , then
  he can buy 12 oranges now @ Rs 4 per orange with same amount.
