Question

In a zoo there are rabbits and pigeons if heads are counted there are 340 heads and if legs are counted there are 1360 legs how many pigeons are there?

Answer 1

Answer:

Suppose there are all the pigeons then total no of heads are 340 and total no of legs are 680. Now, since 380 (1060-680) legs are extra, it means there will be 190 (380/2) rabbits.As we know a rabbit has two extra legs than that of a pigeon.

Answer 2

Answer: B) 150

Explanation:

Suppose there are all the pigeons then total no of heads are 340 and total no of legs are 680.

Now, since 380 (1060-680) legs are extra, it means there will be 190 (380/2) rabbits.As we know a rabbit has two extra legs than that of a pigeon.

Therefore, number of rabbits =190

and number of pigeons = 340- 190 = 150
