A) 70
B) 28
C) 66
D) 40
Correct Answer: A
Solution :
When works are same So, 12 men \[\times \] 36 = 18 women \[\times \] 60 5 women= 2 men 20 women = 8 men Now, 8 men and 20 women or 16 men work done in 1 day \[=\frac{1}{20}\] 1 man can work done in 1 day \[=\frac{1}{20\times 16}\] \[\therefore \]Remaining work \[=1-\frac{16\times 20}{36\times 12}\] \[=1-\frac{20}{27}=\frac{7}{27}\] So, \[\frac{1}{60}\] piece of work can complete in 1 day = 18 women Then, \[\frac{7}{27}\]piece of work can complete in 1 day \[=\frac{18\times 60\times 7}{27}\] = 280 women Hence\[\frac{7}{27}\]piece of work can complete in 4 days \[=\frac{280}{4}\]women \[=70\] womenYou need to login to perform this action.
