Question

please say the answer​

Answer 1

Answer:

number of white balls=3

number of blue balls=2*3=6

number of red balls=6*2=18

conformation = 3+6+12=18+9=27

Step-by-step explanation:

let the number of white balls be x

so no. of blue ball is 2x

so no. of red ball is 3*blue balls =3*2x =6x

total no. of balls =27

therefore

x+2x+6x=27

9x=27

x=3

Answer 2

1) Step-by-step explanation

Let the number of white balls = x

⇒the number of blue balls = 2x

⇒the number of red balls = 3 X 2x= 6x

⇒ x + 2x + 6x = 27

⇒9x=27

⇒ x= 3

the number of white balls = x= 3

⇒the number of blue balls = 2x= 6

⇒the number of red balls = 3 X 2x= 6x = 18

2) let the number be x

Given 2x = x/2 +45

⇒2x - x/2 =45

⇒$\frac{4x - x}{2} = 45$

⇒$\frac{3x}{2} =45$

⇒3x= 45 X 2

⇒$x =\frac{45 X 2}{3}$

⇒ x = 15 X 2 = 30
