Directions (49-63) : What will come in place of question mark (?) in the given questions ?

25% of \( \Large 16 \times \left(15 - ?^{2}\right)^{3} = 256 \)

A) 15
B) 13
C) 9
D) 11
E) 7

Correct Answer:




D) 11

Description for Correct answer:
25% of \( \Large 16 \times \left(15 - ? \right)^{3} = 256 \)

=>\( \Large \frac{25}{100} \times 16 \times \left(15 - ?\right)^{3} = 256 \)

=>\( \Large \left(15 - ?^{3}\right) = 16 \times 4 =64 \)

\( \Large 15 - ? = 4 => ? = 11 \)
