Question

A farmer has a certain number of animals out of these one fifth are cows, thrice the square root of
the total number are buffaloes and remaining 5 are goats. How many animals does he have

Answer 1

Answer:

He has 25 animals.

Step-by-step explanation:

let total number of animals =x

according to the question

x/5+3$\sqrt{x}$+5 = x

on solving we get,

3$\sqrt{x}$ = 4x/5-5

squaring on both sides and rearranging the terms we get the following equation

16$x^{2}$-425x+625=0

finding the roots we get x=25

                                       x=1.25

As x cannot be 1.25

x=25

so total animals are 25
