Question:

Answer 1

Answer:

The number of red balls, in the beginning, is 47.

Step-by-step explanation:

According to the question,

• Luke gains 2 blue balls, losing 3 red balls every day.  
• He seems to have similar amount of blue as well as red balls forward to 5 days.  
• He does indeed have twice quite so many red balls as blue balls forward to 9 days.

Should let the number of blue balls will be "x" in the beginning and indeed the number of red balls will be "y".

After five days,

⇒  $x + 10 = y - 15$ ...(equation 1)

After nine days,

⇒  $x + 18 = 2 ( y - 27 )$ ...(equation 2)

On applying subtraction between the above two equations, we get

⇒  $8 = y - 39$

⇒  $y = 47$
