Question

If nC12 = nC8, then n is equal to

Answer 1

nC12 = nC8

n/ 12 ( n - 12 ) = n / 8 ( n - 8 )

12 = n - 8

n = 12 + 8 = 20

n = 20.

Answer 2

Answer:

Value of n is 20.

Step-by-step explanation:

Given:   $^nC_{12}=^nC_{8}$

To find: Value of n

We know that,

$If\:^nC_x=^nC_y$

then x = y or n = x + y

here,

12 ≠ 8

So, n = 12 + 8 = 20

Therefore, Value of n is 20.
