A piece of an alloy of mass 96 gm is composed of two metals whose specific gravities are 11.4 and 7.4. if the weight of the alloy is 86 gm in water, find the mass of each metal in alloy.

The ratio of zinc and copper in an alloy is 7:9. If the weight of copper in the alloy is 11.7 kg, find the weight of zinc in it.

The ratio of zinc and copper in an alloy is 7:9. It the weight of the copper in the alloy is 11.7 kg,find the weight of the zinc in the alloy.

The ratio of zinc and copper in an alloy is 7: 9. It the weight of the copper in the alloy is 11.7 kg, find the weight of the zinc in the alloy.

When equal volumes of two metal are mixed together, the specific gravity of alloy is 4. When equal masses of the same two metals are mixed together the specific gravity of the alloy is 3. calculate the specific gravity of each metal.

There is a cavity inside a piece of metal of mass 237.3g. The apparent weight of the piece of metal immersed completely in water is 192.1gxxg . If the density of the metal is 7.91g*cm^(-3) , then find the volume of the cavity.
