Question

at a certain time in Gir forest of Gujarat the number of heads and the number of legs of lion and human visitors were counted and it was found that there were 53 heads and 148 legs find the number of lions and humans in forest

Answer 1

let the no. of lions be x
no. of humans be y
so x+y =53
and 4x+2y=148 i.e., 2x+y=74
solving both equations x=21
and y= 53-21=32

Answer 2

x+y=53 , 2x+4y=148 ,x+2y= 74, y=21 x=32
