Question

there are 338 cows and goats on a farm .. 3/3 of cows are equal to the 1/5 of goats of the farm. how many cows are there on the farm ?

Answer 1

Here
Suppose x = no. of cows and y = no. of goats(on the farm)
Given data,
x+y = 338............. 1)
$3 \times x \div 3$
= y/5...............2)

From eq..... 2) we get, the value of x
x = 3y/15.......3)

put this value of x in eq. 1 we get,

3y/15 + y = 338

3y + 15y = 5070

18y = 5070

y = 281.67

x + 281.67 = 338

x = 56.33

Hope it will help
