Question

If Raman completes $\frac{1}{2}$ of a work in one day, how many days are required to complete the whole work?

• A. $\frac{1}{2}$ day
• B. 2 days
• C. 1 day
• D. 4 days

Answer 1

The correct option is B

2 days

Consider the whole work as 1

Fraction of work completed in one day = $\frac{1}{2}$

Hence, number of days needed to complete the whole work = $\frac{1}{\frac{1}{2}}$

= $\frac{1\times 2}{1}$ = 2
