Question

in a box of white and blacks balls, it has 95 black balls . if 8/27 of all the balls in a box are white. how many balls are there in a box? ​

Answer 1

Answer:

There are 135 balls in the box.

Step-by-step explanation:

Let the number of black balls be 'b'

Let the number of white balls be 'w'

Let the total number of balls in the box be 'x'

b = 95

w = 8/27 of x

b = total - w

b = 1 - (8/27) of x

b = 19/27 of x

b = 19/27 of x = 95

19/27 of x = 95

x = 95 x 27

19

x = 5 x 27

x = 135

Answer 2

Answer:

The number of balls in the box = 135

Step-by-step explanation:

Given,

A box contains white and black balls

Number of black balls = 95

The fraction of the white balls in the box = $\frac{8}{27}$

To find,

The total number of balls in the box

Solution:

Let 'x' be the total number of balls in the box

Since the fraction of white balls in the box = $\frac{8}{27}$ and there are only white and black balls

The fraction of black balls in the box = 1 -  $\frac{8}{27}$ = $\frac{27-8}{27} = \frac{19}{27}$

The number of black balls in the box = $\frac{19}{27} x$

Since the number of black balls in the box  = 95 we have

$\frac{19}{27} x$ = 95

x = $\frac{95X27}{19}$

= 5×27 = 135

The number of balls in the box  = 135

Answer:

The number of balls in the box = 135
