Answer 1

Answer:

A group of animals contains some deer & some hens. The total number of their heads is 15 & the total number Of their legs is 50. What is the number of deer in the group?

Lets put this in mathematical form,

let the number of Hens be ‘H’

and number of Deer be ‘D’

note: deer have 4 legs and hen have 2 legs

Given : H + D = 15; H = 15-D;

2H + 4D = 50;

2(15 - D) +4D =50

30–2D+4D = 50

2D = 20

D = 10

H = 15 -D

H = 15–10 = 5

ANS: therefore, there are 10 Deer and 5 Hen in a group of animals.
