Correct Answer: 10 days
Solution : Let the time Bhavana takes to complete the work as B. Since Bhavana is 40% more efficient than Reshma, she can complete the work in $\frac{100\%}{140\%}$ = $\frac{5}{7}$th of the time that Reshma takes. ⇒ B = $\frac{5}{7} × 14$ ⇒ B = $10$ Hence, the correct answer is 10 days.
