Answer : 3. "12"
Explanation :
Answer: C) 12 Explanation: Let the number of buffaloes be x and number of ducks be y. Now, number of heads = x+y Number of legs = 4x+2y .......(1) But given that legs = 2(x+y)+24 ......(2) solving (1) & (2),we get 4x+2y=2x+2y+24 --> x=12. Therefore number of buffaloes =12
