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.

Two metallic wires of the same metal whose masses are 12g and 18g have lengths in the ratio 3:4 .Their resistances are in the ratio

When equal volumes of two metals 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 not becomes 3. find specific gravity of each metal? (specific gravity =("density of substance")/("density of water"))
