(0.006 ÷ ?) + (0.004 ÷ 0.04) + (0.03 ÷ 0.3) = 0.3
Formula used:
Let the unknown value be x.
Calculation:
(0.006 ÷ x) + (0.004 ÷ 0.04) + (0.03 ÷ 0.3) = 0.3
⇒ (0.006 ÷ x) + 0.1 + 0.1 = 0.3
⇒ (0.006 ÷ x) + 0.2 = 0.3
⇒ (0.006 ÷ x) = 0.3 - 0.2
⇒ (0.006 ÷ x) = 0.1
⇒ x = 0.006 ÷ 0.1
⇒ x = 0.06
∴ The correct answer is option (3).
