Directions (46-60) : What should come in place of question mark (?) in the following questions ?

\( \Large \frac{\sqrt{ \left(15 + 24 x 0.5\right) }}{\sqrt{10.2 \div ?}} \) = 3


A) 2.4

B) 5.7

C) 1.7

D) 3.4

E) 6.8

Correct Answer:
C) 1.7

Description for Correct answer:
\( \Large \frac{\sqrt{ \left(15 + 24 \times 0.5\right) }}{\sqrt{10.2 \div ?}} = 3 \)

 \( \Large \frac{\sqrt{15 + 12}}{\sqrt{10.2 \div ?}} = 3 \)

 \( \Large \frac{5}{3 \div ?} = 3\)

 \( \Large \frac{5 x ?}{3} = 3\)

 \( \Large 5 \times ? = 3 x 3 \)

 \( \Large ? = \frac{9}{5} \)

 \( \Large ? = 1.8 = 1.7 \)
