Solution

The correct option is D
6

Work done by Karan in a day = $\frac{1}{8}$

Work done by Sarosh in a day = $\frac{1}{4}$

Work done by Karan and Sarosh together in a day = $\frac{1}{8} +$ $\frac{1}{4}$

= $\frac{3}{8}$

Time taken by them to complete the work = $\frac{8}{3}$ days

Time given to them = 6 days.
