Q.

A.
120
B.
150
C.
170
D.
180
View Answer
Correct choice: B
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
