Question
In a farm, there are some cows and some chickens, only.
If the total number of heads counted in the farm is 48 and total number of feet counted is 140, then find the number of cows in the farm.Solution
Let number of cows in the farm = ‘x’ And, total number of chickens in the farm = ‘y’ So,
x + y = 48 ---- (1) And,
4x + 2y = 140 So,
2x + y = 70 ---- (2) On subtracting Equation (1) from Equation (2), we get x = 22 So, number of cows in the farm = 22
