A) 17
B) 18
C) 19
D) 20
Correct Answer: C
Solution :
Given, number of ladies \[{{W}_{1}}=76\] The number of days to complete the work, \[{{D}_{1}}=33\] Let number of ladies who did not report for the work = x By given condition, \[{{W}_{2}}=76-x\] and \[{{D}_{2}}=44\] \[\because \] \[{{W}_{1}}{{D}_{1}}={{W}_{2}}{{D}_{2}}\] \[\therefore \] \[76\times 33=(76-x)\times 44\] \[\Rightarrow \] \[76-x=\frac{76\times 3}{4}=19\times 3\] \[\Rightarrow \] \[x=76-57=19\]You need to login to perform this action.
