For making engines, the alloy should containing 10% carbon and at least 30% iron. In how many different ways can we prepare this new alloy by mixing at least two of the given alloys?
As the new alloy should contain 10% carbon and only two alloy contains 10% carbon i.e. A1 and A3. Hence, only by mixing A1 and A3 a new alloy with 10% carbon can be formed. Hence, there is only one way.
