Question

A and B are two alloys of gold and copper prepared by mixing metals in the ratio 7 : 2 and 7 : 11 respectively. If equal quantities of the alloys are melted to form a third alloy C, then the ratio of gold and copper in…

Accepted Answer

Option C. 7 : 5. Answer & Solution Answer: Option C Solution: & Gold in C & = ( 7/9 + 718 )\, units & = 7 6\, units & Copper in C & = ( 2/9 + 1118 )\, units & = 5/6\, units & Gold: Copper & = 7/6:5/6 & = 7:5

A and B are two alloys of gold and copper prepared by mixing metals in the ratio 7 : 2 and 7 : 11 respectively. If equal quantities of the alloys are melted to form a third alloy C, then the ratio of gold and copper in alloy C will be.
