(0.004 ÷ ?) + (0.002 ÷ 0.02) - (0.03 ÷ 0.3) = 0.1
Calculation:
(0.004 ÷ ?) + (0.002 ÷ 0.02) - (0.03 ÷ 0.3) = 0.1
Let us replace '?' as 'x'
⇒ (0.004 ÷ x) + (0.002 ÷ 0.02) - (0.03 ÷ 0.3) = 0.1
⇒ (0.004 ÷ x) + (0.1) - (0.1) = 0.1
⇒ 0.004 ÷ x = 0.1
⇒ \(4 \over 1000\) = \(1 \over 10\)x
⇒ \(40 \over 1000\) = x
⇒ \(1 \over 25\) = x
⇒ x = 0.04
∴ The value that should come in the place of '?' is 0.04.
