Find the percentage blue and white balls in the box ?
Solution:-
A box contain blue and white ball the ratio 3:7
Let they be 3X and 7X
The number of blue balls =3X
The number of white balls = 7X
Total number of balls in a box = 3X+7X = 10X
Percentage of blue balls in the box =
(No. of blue balls /Total No. of balls )×100
=>(3X/10X)×100
=>(3×100)/10
=>30%
The percentage of blue balls in the box = 30%
The percentage of white balls in the box
=(No. of white balls /Total No. of balls )×100
=>(7X/10X)×100
=>(7×100)/10
=>70%
The percentage of white balls in the box = 70%
Answer:-
The percentage of blue balls in the box = 30%
