• 4. A shopkeeper charges 12 rupees for a bunch of cakes. Anuj bargained to the shopkeeper and got two extra ones, and that made them cost one rupee for dozen less than first asking price. How many cakes did Anuj receive in 12 rupees?
  a) 10
  b) 14
  c) 18
  d) 16
  
  
  
  
  Solution:
  Let the number of cakes = ‘x’ or ‘x/12’ dozen
  So, x/12 cost Anuj 12 rupees, or 1 dozen cost him = 144/x rupees
  Now, he gets two extra = 144/(x+2) in 1 rupees less,
  => 144/x – 144/(x+2) = 1
  => On putting 16, the equation is satisfied, hence the answer.
