Question

One-third of the herd of cows are grazing in the field, 20 less than half of them are near the river. The remaining 35 are tied with the trees. Find the total number of cows in the herd.

Answer 1

Hey!!!!

As promised I'm here,

____________

let the total number of cows in the herd be x.

Then ATQ,

$\frac{1}{3} x + \frac{1}{2}x - 20 + 35 = x$


$= > \frac{1}{3} x + \frac{1}{2} x - x = - 15$

$= > \frac{2x + 3x - 6x}{6} = - 15$

$= > - x = - 90$

$= > x = 90$

Thus there are 90 cows.

Answer 2

Solution:-
let , total cows is = x
given , grazing = x/3
near rive = (x/2-20)
tied with the treea = 35

acourding to quetion :- total cows is

x/3 +x/2-20 +35 = x

= (2x+3x-6x)/6 = -15

= -x = -90

= [x= 90]

(total number of cows in the herd =90 ).ans
