A) \[(p+r)\,\text{days}\]
B) \[\frac{mp}{m+r}\,\text{days}\]
C) \[\frac{p}{m+r}\,\text{days}\]
D) \[\frac{m+r}{p}\,\text{days}\]
Correct Answer: B
Solution :
\[\overset{\mathbf{Men}}{\mathop{_{(m+r)}^{m}\mathop{\uparrow }_{{}}^{{}}}}\,\] \[\overset{\mathbf{Days}}{\mathop{_{x}^{p}\mathop{\downarrow }_{{}}^{{}}}}\,\] \[\therefore \] \[\frac{x}{p}=\frac{m}{m+r}\] \[\Rightarrow \] \[x=\frac{mp}{m+r}\,\text{days}\]You need to login to perform this action.
