Question

In an examination, each question fetches 1 mark for correct answer. If a student responds incorrectly, one-third of the mark is deducted from the total marks. For each incorrect answer, the mark deducted is

• A. $0.3$
• B. 3
• C. 1
• D. $0.\overline{3}$

Answer 1

The correct option is D $0.\overline{3}$

For each wrong response, one-third of the full marks of the question is deducted.
One-third of 1 mark = $\frac{1}{3}$
Using long division,

we get quotient = 0.3333 and so on. It is a non-terminating and repeating decimal. It can be represented as $0.\overline{3}$
