a blue ball is 3times the red ball ,then the number of blue balls in a box is​

Answer 1

Answer:

24 blue balls

Step-by-step explanation:

let number of blue balls = n

... total balls = (n + 8)

P(blue ball) n n+8

P(red ball) = 8 n+ 8

as per question,

P(blue ball) = 3× P(red ball)

n n+8 = 3 x 8 n+ 8

... n = 24

Answer 2

Answer:

24

Step-by-step explanation:

written that blue is 3 times of red, so multiply 3 by 8
