In a basket, the number of blue, red and green balls are in the ratio 4 : 7:9. if there are a total of 960 balls, then find the number of green balls.

The ratio of the numbers of blue to red balls in a bag is constant. When there were 44 red balls, the number of blue balls was 36. If the number of blue balls is 54, how many red balls will be in the bag?

A bag contains 6 green balls, some black and red balls. Number of black balls is as twice as the number of red balls. Probability of getting a green ball is thrice the probability of getting a red ball. Find (i) number of black balls (ii) total number of balls.

In a bag the ratio of red balls to green balls is 15 : 26 . If 12 more green balls are added to the bag the ratio of red balls to green balls will become 1: 2 . How" many red balls are there in the bag ?

A box contains 4 red balls, 5 green balls and P white balls. If the probability of randomly picked ball from the box to be a red ball is 1/3 , then find the number of white balls.

A bag contains 10 red 5 blue and 7 green balls. A ball is drawn at random. Find the probability of this ball being a (i) red ball (ii) green ball (iii) not a blue ball

A bag contains 10 red 5 blue and 7 green balls. A ball is drawn at random. Find the probability of this ball being a (i) red ball (ii) green ball (iii) not a blue ball

There are 6 red and 8 green balls in a bag. 5 balls are drawn at random and placed in a red box. The remaining balls are placed in a green box. What is the probability that the number of red balls in the green box plus the number of green balls in the red box is not a prime number?
