Back to Exercise
There are deer and peacocks in a zoo. By counting heads they are 80. The number of their legs is 200. How many peacocks are there?
- A 10
- B 20
- C 40
- D 60 Correct
Correct Answer: Option D
Let x and y be the number of deer and peacocks in the zoo respectively.
Then, x + y = 80 ------------------> (i)
4x + 2y = 200 or 2x + y = 100 ---------> (ii)
Solving (i) and (ii), we get : x = 20, y = 60.
