Question

There are some parrots and tigers in a forest. If the total number of animal heads in the forest is 858 and the 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 these

Answer 1

The correct option is E None of these

If the number of parrots in the forest is x, then number of tigers = 858 - x
$\therefore x\times 2+(858-x)\times 4=1746$
$\Rightarrow 2x=3432-1746=1686$
$\Rightarrow x=\frac{1686}{2}$
$=843$
