Direction: There are three boxes P, Q and R which consists of Red, Blue and Green colour balls. Total number of blue balls in all three boxes together is 9 and total number of balls in all the boxes together is 32.

In Box P: The probability of choosing a Blue ball is 1/4 and the number of red balls is 2 more than the number of blue balls.

In Box Q: Total number of balls is 10 and the ratio of probability of getting a Blue and a Red ball is 2 : 3. Also the sum of Blue and Green balls is 4 more than the number of red balls.

In Box R: Total number of balls is 10 and the probability of getting a red is 1/5 less than the probability of getting a blue.

If ‘x’ red balls are shifted from each of the boxes P and R to box Q then probability of drawing a red ball from box Q increases by 7/60. Find the value of x.
