| There are some parrots and some tigers in a forest. If the total number of animal heads in the forest are 858 and total number of animal legs are 1746, what is the number of parrots in the forest? |
A) 845
B) 833
C) 800
D) Cannot be determined
E) None of the above
Correct Answer: E
Solution :
| Let the number of parrots and tigers be x and y, respectively. |
| Then, according to the question, |
| \[x+y=858\] |
| and \[2x+4y=1746\] |
| On solving these for x and y, we get |
| \[2y=30\]\[\Rightarrow \]\[y=15\] |
| \[\therefore \] Number of parrots \[=(x)=858-15=843\] |
