There are some rabbits and peacocks in a zoo. The total number of their heads is 60 and total number of their legs is 192. Find the number of total rabbits?
Select:
A) 22
B) 87
C) 26
D) 19
E) 36
Explanation:   Let the number of rabbits and peacocks be 'r' and 'p' respectively. As each animal has only one head, so r + p = 60 --- (1)   Each rabbit has 4 legs and each peacock has 2 legs. Total number of legs of rabbits and peacocks, 4r + 2p = 192 --- (2)   Multiplying equation (1) by 2 and subtracting it from equation (2), we get   =&gt; 2r = 72 =&gt; r = 36.   Answer: 36
