There are two alloys of copper and aluminium, alloy A has 40% aluminium and alloy B has 10% copper. In what ratio should these alloys be mixed so that the cost of total copper becomes equal to the cost of total aluminium in the mixture? (The cost price of aluminium is Rs. 200 per kg and cost price of copper is Rs. 500 per kg)
Two alloys used to manufacture the third alloy. The first alloy contains Copper and Zinc only, and the second alloy contains Aluminium and Copper only. The Copper content in the two alloys is 40% and 60% respectively. The Zinc content in the new alloy should be between 30 to 40%. How much will be the minimum and maximum Copper content in the new alloy?
Amal preparing an alloy by mixing the other two alloys. The first alloy contains zinc and carbon in the ratio of 1 : 3 and the second alloy contains Aluminium and zinc in the ratio of 2 : 3 (both these alloys have only these elements in the solution). If the new alloy contains Aluminum and Zinc in the ratio of 3 : 5, what is the percentage of carbon in the new alloy?
An alloy A contains two elements, copper and tin in the ratio of 2 : 3, whereas an alloy B contains the same elements in the ratio of 3 : 4. If 20 kg of alloy A, 28 kg of alloy B and some more pure copper are mixed to form a third alloy C which now contains copper and tin in the ratio of 6 : 7, then what is the quantity of the pure copper mixed in the alloy C?
An alloy A contains two elements, copper and tin in the ratio of 2 ∶ 3, whereas an alloy B contains the same elements in the ratio of 3 ∶ 4. If 20 kg of alloy A, 28 kg of alloy B and some more pure copper are mixed to form a third alloy C which now contains copper and tin in the ratio of 6 ∶ 7, then what is the quantity of the pure copper mixed in the alloy C?
Each question comprises of a statement and two conclusions I) and II). Assuming that the statement is true, which of the conclusions follow logically from the statement? Statement: Because of growth in production of Aluminium by National Aluminium Company, India has become self-sufficient in Aluminium. Conclusion: I) Previously India had to import Aluminium. II) At this rate, India may start exporting Aluminium.
