Solution

The correct option is D
10

$H e r e, n = \sum f_{i} = z + 5 + 6 + 1 + 2 = 14 + z$
$G i v e n : \sum f_{i} = 24$
$∴ n = \sum f_{i} = 14 + z = 24$
$\Rightarrow z = 24 - 14 = 10$ .

$H e r e, n = \sum f_{i} = z + 5 + 6 + 1 + 2 = 14 + z$
$G i v e n : \sum f_{i} = 24$
$∴ n = \sum f_{i} = 14 + z = 24$
$\Rightarrow z = 24 - 14 = 10$ .
