Ina zoo , each pigeon has 2 legs, and each rabbit has 4 legs. The head count of the two species together is 12 , and the leg count is 32. How many pigeons and how main rabbits are there in the zoo ? Correct Answer 8 & 4
A/Q, x + y = 12 or, 2x + 2y = 24 ....................... (1) 2x + 4y = 32 ............................ (2) (2) - (1) we get, 2y = 8 or, y = 4 ......(3) Now, from (1) and (3), we get, x + 4 = 12 or, x = 12 - 4 or, x = 8
