Question

The total number of lions and peacock in a certain zoo is 50.The total number of their legs is 140.Then find the number of lions and peacock in the zoo.

Answer 1

Answer:

lions are 20 and peacocks are 30

Step-by-step explanation:

let no. of lion be = x

let no. of peacock be = y

x+y =50 (given) ... i

lion has 4 legs, therefore no. of legs of lion be = 4x, similarly peacock legs would be = 2y

4x+2y = 140

2(2x+y) = 140

2x+y = 70...ii

eliminating i from ii

2x+y=70

- x+y =50

we get x=20

then y would be 30
