Why do Giraffes have long tung ???

  Long tung is basically a surviving tool for living in tall., spiky trees.


Giraffe tongue is 45 to 50 m long  !!!


Giraffe has long tongue mainly for these reasons  ----


1.  Reaching food


2.  Protecting themselves 


3.  Keeping calm


            Giraffes eat mostly Acacia trees. These trees are tall and covered with thorns.

              Giraffes can reach this much height and their long tung lets it strips leaves between the thorns without getting poked  !!!

             Tongue is super tough and muscular. Thick leathery skin +  lots of saliva helps it slide past thorns without getting cut.



              With long tongue, giraffes clean their face, eyes and ears   !!!

Question 


While dividing 80 Rs between 4 friends, if 3 receive 22 each how much remaining friend get ??


14             22             8                16

If Rs 80  get equally divided between 4  friends, each one would get Rs 20  !!!


But alas ,  that's not the case  here ......


Out of  4,  3 people are getting  Rs 22 each.

If 3 people get 22 Rs each,


Sum would be    22  +    22    +   22

Out of 80 Rs,  3 are together getting   Rs  66  !!!


==>>  Fourth friend will get


==>>   80  -  66

==>>   14 Rs   !!!!
