Gold is 10 times as heavy as water and copper is 5 times as heavy as water. In what ratio should these be mixed to get an alloy 8 times as heavy as water?	Options.
A) 3:2 B) 1:2 C) 3:1 D) 5:2 E) 4:3
G = 10W   C = 5W   Let 1gm of gold mixed with x gm of copper to get 1+x gm of the alloy   1gm gold + x gm copper = x+1 gm of alloy   10W+5Wx = x+1 * 8W   10+5x = 8(x+1)   x = 2/3   Ratio of gold with copper = 1:2/3 = 3:2   3:2nswer is 3:2
