A) 32
B) 40
C) 48
D) 64
E) 72
Correct Answer: B
Solution :
Ratio of efficiency of one woman to one man \[=\frac{4}{25}:\frac{5}{20}=16:25\] \[\Rightarrow 16men=25women\] \[\therefore \] 8 men + 10 women\[=\frac{25}{2}+10\] = 22.5 women Now, using \[{{M}_{1}}{{D}_{1}}={{M}_{2}}{{D}_{2}}\] Now, \[22.5\times \frac{16}{3}=x\times 3\] \[\therefore x=\frac{22.5\times 16}{9}=40\]You need to login to perform this action.
