What will come in place of the questions mark (?) in the following equations?

\(\sqrt {0.0289} \times 12 \div 1.5 = ?\)

A 1.36

B 2.06

C 13.90

D 14.80

E None of these

Solution

Correct Answer: Option A

Given expression:

\(\begin{array}{l} \Rightarrow ? = \sqrt {0.0289} \times 12 \div 1.5\\ = \sqrt {0.0289} \times 8\\ = \sqrt {289 \times {{10}^{ - 4}}} \times 8 \end{array}\)

= 17 × 10-2 × 8

= 1.36
