Question

a man buy a few parrots,20% of them flew,10% are died,and remain 14 parrots.find the
number of total parrots with language.

Answer 1

Let Man buy= x parrots

20% of them Flew
20% of x
=20/100×x=x/5 Parrot

Parrot Flew=x/5

Parrot Died=10%
10% of x
10/100×x
x/10

Parrot Died=x/10

Remain=14

MEANS
Total Parrot-(Died +flew)=14

x-(X/5+X/10)=14
x-3x/10=14 (Lcm=10)
10x-3x/10=14. (lcm=10)
7x/10=14
X=14×10/7
x=20

Total Parrots=20
