Bantams only count as 1/3 of a whole chicken. In this example, neither the value of x nor the value of y was the answer to the question. The rules of chicken math: Every keeper has a slightly different take but these are general rules to get you started. So, the farm has (130 - 70) = 60 more chickens Choice C is the correct answer to this linear equations word problem.Īs a good practice in any GMAT question, after solving the system of equations and computing values for the unknown, check whether further action has to be taken to get the answer. Note:The question is "How many more chickens were there in the farm?" So, the farm has 130 chickens and 70 pigs. 'x' is the number of chickens in the farm. (2) Step 2 of solving this GMAT Linear Equations Question: Solve the system of linear equations So, the sum of the number of legs of chickens and the number of legs of pigs is 540. The count of the legs in the farm is 540. 'x' chickens will therefore, have 2x legs and 'y' pigs will have 4y legs. Linear Equation with Two Unknowns can be used to solve Chicken and Rabit Problem (R for rabbits, and C for chicken) For heads: For legs: Let’s plug into the second equation, and we get: so so. So, the sum of the number of chickens and pigs is 200.Įach chicken has 2 legs and each pig has 4 legs The count of the heads in the farm is 200. Therefore, number of heads will be the same as the sum of the chickens and pigs in the farm. Let the number of pigs in the farm be 'y'.
We can express the problem using Math equations: We know a rabbit has four legs and a chicken has two legs. Let the number of chickens in the farm be 'x'.
