"To err is human; to forgive, divine."
- Alexander Pope
23. 

The least among the following is:

[A]. 0.2[B]. 1 ÷ 0.2
[C]. 0.2[D]. (0.2)2

Answer: Option C

Explanation:

1 ÷ 0.2 = 1 = 10 = 5;
0.2 2

0.2 = 0.222...;

(0.2)2 = 0.04.

0.04 < 0.2 < 0.22....<5.

Since 0.04 is the least, so (0.2)2 is the least.
