Hey there,
Since the blue balls is x so total number of balls=4+x
Blue balls/Total balls=1/2
x/4+x=1/2
2x=4+x
Therefore x=Number of blue balls=4
PLEASE MARK AS BRAINLIEST IF HELPFUL!!!

In the right angled issoceless traingle, if its sides are increased by 75% then the percentage change in its area is
Ye wala
Here, ratio of the length of the sides of new triangle to the length of the corresponding sides of original triangle = 1:2
And triangle CDE ~ triangle ABC ( by AAA Similarity criterion)
So, area ( triangleCDE) : area( triangle ABC)
= 1 : 4
So, If area of smaller triangle is x then the area of larger triangle = 4x
Decrease in area 4x -x =3x
So, percentage decrease
= ( decrease in area/ Original area) * 100
= (3x / 4x)*100
= 75%

Bhai iska option h 306.25%,103.125%,206.25%,105.125%
sorry i increased the area by 75% and got 50% increase in sides
