Ans. = Option (C).

Tin is present only in the second alloy.

8+5=13
Assume 13 kg of both the alloys are melted together.

Weight of tin in the resulting alloy =13×5/13=5 kg
Total weight of the resulting alloy =13+13=26 kg

i.e., in 26 kg of the resulting alloy, weight of tin is 5 kg.

Therefore, weight of tin in the resulting alloy per kg
=5/26 kg
