A) 2 : 1
B) 2 : 3
C) 3 : 2
D) 1 : 2
Correct Answer: A
Solution :
Ratio of copper and zinc = 5 : 2. Total weight of alloy = 17500 g \[\therefore \] Weight of copper \[=\frac{5}{7}\times 17500=12500\,\,g\] \[=17500-12500=5000\,\,g\] 1250 g of zinc is mixed with the alloy. \[\therefore \] Total weight of zinc\[=5000+1250=6250\,\,g\] \[\therefore \] New ratio = 12500 : 6250 = 2 : 1You need to login to perform this action.
