A) \[25:33\]
B) \[33:25\]
C) \[15:17\]
D) \[17:15\]
Correct Answer: C
Solution :
Let \[1\,\,kg\] of each of the alloys \[A\] and \[B\] be mixed together. In alloy\[A\], Quantity of gold\[=\frac{5}{8}kg\]. Quantity of coppers\[=\frac{3}{8}kg\]. In alloy\[B\], Quantity of gold\[=\frac{5}{16}kg\]. Quantity of copper\[=\frac{11}{16}kg\] \[\therefore \] Required ratio \[=\left( \frac{5}{8}+\frac{5}{16} \right):\left( \frac{3}{8}+\frac{11}{16} \right)\] \[=\frac{15}{16}:\frac{17}{16}=15:17\]You need to login to perform this action.
