Four tenths => 0.40

Five thousandths => 0.005

Average of 0.005 & 0.40 => \(\frac{( 0.005 + 0.40 )}{2}\) = 0.2025

Hence answer will be D. 0.2025 :lol: :P

Four tenths: 4 * \(\frac{1}{10}\) = 0.4

Five thousandths: 5 * \(\frac{1}{1000}\) = 0.005

Average: \(\frac{(0.4 + 0.005) }{ 2} = \frac{0.405}{2}\) = 0.2025
