Question

The ratio of balls in three boxes is 6:8:9. In what ratio should the balls in the second and third boxes be increased, so that the final ratio becomes
1:3:4?​

Answer 1

The ratio is 2 : 3

Step-by-step explanation:

Given

The final ratio is 1 : 3 : 4

Initial ratio is 6 : 8 : 9

Scaling up the final ratio we get

1 : 3 : 4 is same as 6 : 18 : 24

Initial ratio in 2nd and 3rd boxes = 8 : 9

Final ratio = 18 : 24

So balls in the 2nd and 3rd boxes have been increased by 10 and 15 respectively

Thus, the ratio in which they have been increased

= 10/15

= 2/3

Hope this answer is helpful.
