If 4 kg of an alloy made of 1/4th iron and rest is mixed with 6 kg of another alloy made of 2/3rd iron and rest tin, find the ratio of iron to tin in the resultant mixture.
-
- 1 : 1
- 2 : 1
- 1 : 2
- 3 : 2
Correct Option: A
Total quantity of iron = 4 (1 / 4) + 6 (2 / 3) = 1 + 4 = 5 kg.
Total quantity of tin = (4 + 6) – 5 = 5 kg.
In the resultant mixture, iron : tin = 5 : 5 or 1 : 1
