due to a price hike of 20%,4kg less tea is available for Rs 120.What is the original price of the tea?

• Rs. 5/kg.......
  let, original price of x kg is 120. then original price per kg. is 120/x
  after hike of 20% , price of (x-4)kg is 120..i.e price per kg is 120/(x-4)
  so , according to price hike,
  { (120/(x-4)) - (120/x) } / (120/x)= 20/100
  if we solve this we shall get x=24kg
  so,original price of tea is Rs. 5/kg
