Permutation Probability

A boss decides to distribute Rs. 2000 between 2 employees. He knows X deserves more that Y, but does not know how much more. So he decides to arbitrarily break Rs. 2000 into two parts and give X the bigger part. What is the chance that X gets twice as much as Y or more?

Detailed Solution. N is a three digit multiple of 7. N could be 105, 112, 119, 126…..994. Or, 15 × 7, 16 × 7…..142 × 7. Or there are 142–14 = 128 numbers. Within these we need to locate the multiples of 5. Or, we need to isolate multiples of 35. Or, we need to see how many numbers there are in ...

Detailed Solution. First A.P., a = 1, d = 4 S2n = 2n/2 [2 x 1+(2n −1)4] S2n = n(2 + 8n – 4) = n(8n – 2) = 8n2 – 2n For the second AP, a = 56, d = 2 Sn = n/2 [2 x 56+(n −1)2] Sn = n/2 [112+2n −2] = n/2 (110+2n) The sum of 2n terms of AP {1, 5, 9, 13, …..} is greater than sum of n terms of A.P. ...
