A) Rs. 375
B) Rs. 750
C) Rs. 500
D) Rs. 2250
Correct Answer: B
Solution :
Suppose C alone could do the work in x days. Then, \[\frac{1}{x}=\frac{1}{4}-\left( \frac{1}{8}+\frac{1}{12} \right)\] \[=\frac{1}{4}-\frac{5}{24}=\frac{1}{24}\] \[x=24\,\,days\] Ratio in work done by A, B and C \[=\frac{1}{8}:\frac{1}{12}:\frac{1}{24}\] \[=3:2:1\] Hence, C's share of money \[=\frac{1}{(3+2+1)}\times 4500\] \[=\frac{1}{6}\times 4500=Rs.\,\,750\]You need to login to perform this action.
