Question

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, then the amount of tin in the new alloy is:(a) 38 kg(b) 44 kg(c) 55 kg(d) 84 kg

Answer 1

The amount of tin in the new alloy is 44 Kg

Answer 2

Quantity of tin in 60 kg of A =

(60∗25)

kg = 24 kg.

Quantity of tin in 100 kg of B =

(100∗15)

kg kg = 20 kg.

Quantity of tin in the new alloy = (24 + 20) kg = 44 kg
