  SAMPLE SOLUTION
  Chapter: Problem:
  • Step 1 of 1
  
  You are given the total number of seats and the total number of wheels when these are a certain number of bicycles and tricycles at a bicycle store. You need to find the number of bicycles and tricycles.
  
  Assume that the number of bicycles and tricycles in the store is b and t respectively.
  
  As each cycle-bicycle as well as tricycle has only one seat and the total number of seats is given as 32, we get
  
  Bicycle has 2 wheels each and a tricycle has 3 wheels each and the total number of wheels is given as 72, we get
  
  Multiplying equation (i) with 2 and subtracting the same from equation (ii), we get
  
  next using equation (i), we get, which gives.
  
  Thus, the number of bicycles and tricycles in the store was 24 and 8 respectively.
