In a zoo, there are deers and ducks. If the heads are counted, there are 180, while the legs are 448. What will be the number of deers in the zoo?

Answer: Option C

Average legs per head = $$\frac{448}{180}$$

Deers : Ducks = 88 : 272
Hence, the number of Deers = $$\frac{180\times 88}{360}$$   = 44
