If only one of the boxes has a green ball, it can be any of the 6 boxes. So, this can be achieved in 6 ways.

If two of the boxes have green balls and then there are 5 consecutive sets of 2 boxes. 12, 23, 34, 45, 56.

Similarly, if 3 of the boxes have green balls, there will be 4 options.

If 4 boxes have green balls, there will be 3 options.

If 5 boxes have green balls, then there will be 2 options.

If all 6 boxes have green balls, then there will be just 1 options.

Total number of options = 6 + 5 + 4 + 3 + 2 + 1 = 21.

10). B

Present age of
ravi = 7x and present age of vinay = 15 x

According to the question, 15x+2 = 2(7x + 2)

15x – 14 x = 4-2 = x= 2

Required Difference = 15x- 7x = 8x = 16 yr
