Question

in a bag containing red, green and pink token, the ratio of red and green tokens was 12 : 35 while the ratio of pink and red tokens was 25 : 18 what was the ratio of green and Pink tokens?

Answer 1

Given :

Ratio of red and green tokens = 35 : 12

Ratio of pink and red tokens = 25 : 18

Finding the common number of red tokens -

12 x 3 = 36

18 x 2 = 36

Now , to get the ratio multiply the given ratio (35 : 12) with 3 and (25 : 28) with 2

(35 : 12) x 3 = 105 : 36

(25 : 12) x 2 = 50 : 36

Now , the ratio of red tokens are equal .

So , the ratio of green and pink is -

= 105 : 50

= 21 : 10

$\bold{Answer: = \: 21 : 10}$

Answer 2

Ratio of green and red tokens = 35: 12

Ratio of pink and red token = 25 : 18

First, we will find the common number of red tokens.

12 × 3 = 36

18 × 2 = 36

(35 : 12)*3 = 105 : 36

(25 : 18)*2 = 50 : 36

Now, the ratio of red tokens in both cases is equal.

the ratio of green and pink = 105 : 50

= 21 : 10

135.

Density= no of fishes / Volume.

Density = 0.5

No of fishes= 30

Volume = No of fishes/ density

Volume = 30/0.5= 60 ft^3

The volume of the tank is calculated by multiplying the three dimensions, that is

The density of water is 62.4 pounds per cubic foot. a cubic foot is 12 inches by 12 inches by 12 inches, hence. Thus your tank is 6048/1728 = 3.5
