A) 11
B) 5
C) 1
D) 9
E) 3

Correct Answer:





E) 3

Description for Correct answer:
\( \Large \sqrt{ \left( \times 3.2 \times \sqrt{625}\right) } = 12\frac{6}{7} \div \frac{?}{14} \)

=>\( \Large \sqrt{144 \times 25} = \frac{90}{7} \div \frac{?}{14}\)

=>\( \Large 12 \times 5 = \frac{90}{7} \times \frac{14}{?} \)

=>\( \Large ? = \frac{90 \times 2}{12 \times 5} =3 \)
