Gold is 10 times as heavy as water and copper is 6 times as heavy as water. In what ratio should these be mixed to get an alloy 8 times as heavy as water?
Choose the correct option:
A) 3:2  B) 1:1  C) 3:1  D) 5:2  E) 4:3
G = 10W   C = 6W   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+6Wx = x+1 * 8W   10+6x = 8(x+1)   x = 1/1=
