Question

20 blue balls and 10 red balls how to increase red ball percent to 40

Answer 1

buy more red balls for increasing it to 40%....you have to add more 10 red balls..

Answer 2

Hi !

Here's your answer, Sir/Madam :-

No. of Blue Balls - 20
No. of Red ones - 10

% to be increased (Red) - 40%

So,

40/100 × 10

= 4

NOW,

10 + 4

= 14

Therefore, 4 balls increase if 40% of 10 balls added.

Hope it helps...
