B) Rs. 11,700
C) Rs. 16,100
D) Rs. 17,100
Correct Answer: D
Solution :
[d] 5 men =7 women \[\therefore \,\,7\,men=\frac{7}{5}\times 7=\frac{49}{5}\]Women \[\therefore \,\,7\]Men+13 women\[=\frac{49}{5}+13=\frac{114}{5}\]women Now, \[\therefore \]7 women =Rs. 5250 \[\therefore \frac{114}{5}\]Women \[=\frac{5250}{7}\times \frac{114}{5}=Rs.\,\,17100\] Alternate Method: 5 Men=7 women Work efficiency of man: Women=7:5 Work efficiency of 5 Men\[=5\times 7=35\] Work efficiency of 7 Men and 13 Women\[=7\times 7+5\times 65=114\] Required amount \[=\frac{5250}{35}\times 114=17100\]
