  • Question
  • In a zoo, there are rabbits and pigeons. If heads are counted, there are 340 heads and if legs are counted there are 1060 legs.How many pigeons are there?


  • Options
  • A. 120
  • B. 150
  • C. 170
  • D. 180

  • Correct Answer
  • 150 

    Explanation

    Suppose there are all the pigeons then total no of heads are 340 and total no of legs are 680. 

     

    Now, since 380 (1060-680) legs are extra, it means there will be 190 (380/2) rabbits.As we know a rabbit has two extra legs than that of a pigeon.

     

    Therefore,  number of rabbits =190

     

    and number of pigeons = 340- 190 = 150
