(a) 0.4 (b) 0.04 (c) 0.004 (d) None of these

Answer 1

The decimal which should be subtracted from 0.1 to get 0.06 can be obtained by subtracting 0.06 from 0.1.

Converting the given decimals into like decimals, we have 0.10 and 0.06.

Now,

$\begin{array}{ccccc}& 0& .& 1& 0\\ -& 0& .& 0& 6\\ & 0& .& 0& 4\end{array}$

∴ Required decimal = 0.1 − 0.06 = 0.04

Hence, the correct answer is option (b).
