A) 15
B) 20
C) 25
D) 30
Correct Answer: A
Solution :
7 men = 10 women \[\Rightarrow \] 1 man \[=\frac{10}{7}\]women \[\therefore \]14 men + 20 women \[=\left( \frac{10\times 14}{7}+20 \right)\]women = 40 women Now, more work, more days More women, less days \[\left. \begin{matrix} \text{Work} & 1 & : & 6 \\ \text{Women} & 40 & : & 10 \\ \end{matrix} \right\}:\,\,:10:x\] Where, x = Number of days \[\Rightarrow \] \[1\times 40\times x=6\times 10\times 10\] \[\Rightarrow \] \[x=\frac{600}{40}=15\,\,\text{days}\]You need to login to perform this action.
