Question

An alloy contains copper and zinc in the ratio 5:3 and another alloy contains copper and tin in the ratio 8:5. If equal weights of both alloys are melted together, then the weight of tin in the resulting alloy per kg will be
  1. 295
  2. 526
  3. 317
  4. 295


Solution

The correct option is B 526
513 of the tin is in 1 kg of alloy.
Since quantity of tin is constant (because the other alloy does not contain tin), therefore there is 513 of the tin in 2
kg of alloy if 1 kg of both alloys is taken.
Hence, there is 526 of tin in 1 kg of alloy.
