  1. 60 kg of an alloy A is mixed with 100 kg of alloy B. If alloy A has lead and tin in the ratio 3 : 2 and alloy B has tin and copper in the ratio 1 : 4, the amount of tin in the new alloy is
    1. 53 kg
    2. 44 kg
    3. 80 kg
    4. 24 kg
Correct Option: B

In 60 kg of alloy A,

5

Tin =
2
× 60 = 24 kg.
5

In 100 kg of alloy B,
Tin =
