If nC12 = nC5, find the value of n.

Asked by Sakshi | 1 year ago |  50

##### Solution :-

We know that if nCp = nCq, then one of the following conditions need to be satisfied:

(i) p = q

(ii) n = p + q

So from the question nC12 = nC5, we can say that

12 ≠ 5

So, the condition (ii) must be satisfied,

n = 12 + 5

n = 17

The value of n is 17.
