What will come in place of the question mark (?) in the following questions ?
$$9\frac{3}{7} + 6\frac{4}{7} - ? = 14\frac{4}{7}$$
Let the unknown quantity be 'p'.
$$9\frac{3}{7} + 6\frac{4}{7} - p = 14\frac{4}{7}$$.
$$\frac{66}{7}+\frac{46}{7}-p=\frac{102}{7}$$.
$$p=\frac{66+46-102}{7}$$.
$$p=\frac{10}{7}$$.
$$p=1\frac{3}{7}$$.
Hence, Option D is correct.
