Question

in a bag of red and blue balls the number of Blue Balls is 2 more than the red balls how many red balls are there in the bag if the total number of balls are 40 please give my answer in full solution ​

Answer 1

Let , the bag contains B number of blue balls.

So, there are 5 red balls and B blue balls.

Total number of balls=B+5

Now drawing a red ball from B+5 balls can be done in 5C1 ways and drawing a blue ball from B+5 balls can be done in BC1 ways.

now , probability of drawing red ball= 5C1/(B+5)C1

probability of drawing blue ball= BC1/(B+5)C1

Given , BC1/(B+5)C1 = 2*5C1/(B+5)C1

therefore B=2*5 =10
