There are some balls of red, green and yellow colour lying on a table....
Analysis:
Let's analyze the given information step by step to determine the number of red balls.

1. There are as many red balls as there are yellow balls. Let's assume the number of red and yellow balls as "x".

2. There are twice as many yellow balls as there are green ones. So, the number of green balls would be "x/2".

3. To find the total number of balls, we add the number of red, yellow, and green balls together. It becomes:
Red balls + Yellow balls + Green balls = x + x + x/2 = 2x + x/2

Solution:
a) The number of red balls is equal to the sum of yellow and green balls.
This statement is not true because the sum of yellow and green balls is x + x/2, which is not equal to the number of red balls (2x + x/2). So, option 'a' is incorrect.

b) The number of red balls is double the number of green balls.
From the above calculation, we can see that the number of red balls (2x + x/2) is indeed double the number of green balls (x/2). Hence, option 'b' is correct.

c) The number of red balls is equal to yellow balls minus green balls.
We cannot determine whether this statement is true or false based on the information given. So, option 'c' cannot be ascertained.

d) The number of red balls cannot be ascertained.
This statement is not true because we have determined that the number of red balls is double the number of green balls. So, option 'd' is incorrect.

Therefore, the correct answer is option 'b' - The number of red balls is double the number of green balls.
