Determine n if
`""^(2n)C_(3):""^(n)C_(3)=12:1` .

Determine n if ( i )^(2n)C_(2):^(n)C_(2)=12:1 (ii) ^2nC_(3):^(n)C_(3)=11:1

If .^(2n)C_(3):.^(n)C_(3)=12:1 , find n.

(i) If ""^(2n)C_(3) : ""^(n)C_(3)= 11 : 1 , find n. (ii) If ""^(2n)C_(3) : ""^(n)C_(2) = 12 : 1 , find n.

If ""^(n)C_(2)= ""^(n)C_(3) , then n = ……….

Find 'n', if ""^(2n)C_(1), ""^(2n)C_(2) and ""^(2n)C_(3) are in A.P.

(i) If ""^(n)C_(8)= ""^(n)C_(2) , find ""^(n)C_(2) . (ii) If ""^(n)C_(10)= ""^(n)C_(12) , determine n and hence ""^(n)C_(5) . (iii) If ""^(n)C_(9)= ""^(n)C_(8) , find ""^(n)C_(17) .

If the ratio ^(2n)C_(3).^(n)C_(3) is equal to 11:1 find n
