Detailed Solution
Download Solution PDFLet the number of bulls be ‘a’ and the number of hens be ‘b’.
So, the total numbers of heads are (a + b) and total numbers of legs are (4a + 2b).
According to question:
(4a + 2b) = 2(a + b) + 48
4a + 2b = 2a + 2b + 48
4a + 2b – 2a – 2b = 48
2a = 48
a = 24
So, the number of bulls is 24.
Hence, ‘24’ is the correct answer.
