1. In a zoo, there are Rabbits and Pigeons. If heads are counted, there are 200 and if legs are counted, there are 580. How many pigeons are there?

A. 90

B. 100

C. 110

D. 120

Solution:

Heads Count = 200
Legs count = 580
Average Legs count for per head =

\frac{580}{200}

\frac{29}{10}

Rabbits : Pigeons =

\frac{9}{10}

\frac{11}{10}

= 9 : 11
Number of Pigeons =

200 \times \frac{11}{20}

= 110
