A person bought a certain number of oranges for Rs. 70. If the price of each orange was Rs. 2 less, he would have bought 4 more oranges for the same amount. What is the number of oranges he bought originally?

• answer=10
  if no. of orange=n
  1 orange @ x rs
  nx=70.......(1)
  nx-n(x-2)=4(x-2).....(2)
  solving n=10

• let number of orange be x.
  and price of each orange be n
  then
  nx=70.....(1)
  and from question
  nx-x(n-2)=4(n-2)...(2)
  after solving equation 1 & 2 we get
  number of orange i.e. x=10
