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?

Assertion 'a': Hardenability of steel can be increased by adding certain alloying elements.
Reason 'r': The alloying elements can provide a fine dispersion of alloy carbides
In an alloy, lead and tin are in the ratio of 2 : 3. In the second alloy, the ratio of same elements is 3 : 4. If equal quantities of these two alloy are mixed to form a new alloy, then what will be the ratio of these two elements in the new alloy?

Consider the following two C code segment. Y and X are one- and two-dimensional arrays of size n and n × n respectively, where 2 ≤ n ≤ 10. Assume that in both code segments, elements of y are initialized to 0 and each element X[i] [j] of array X is initialized to i + j. Further assume that when stored in main memory all elements of x are in same main memory page frame. Code segment 1:                 //initialize elements of y to 0                 //initialize elements X[i] [j] of X to i+j                       for (i = 0; i < n; i++)                                 Y[i] += X[0] [i]; Code Segment 2:                 //initialize elements of Y to 0                 //initialize elements X[i] [j] of X to i+j                        for (i = 0; i < n; i++)                                 Y[i] += X[i] [0]; Which of the following statements is/are correct? S1: Final contents of array Y will be same in both code segments S2: Elements of array X accessed inside the for loop shown in code segment 1 are contiguous in main memory S3: Elements of array X accessed inside the for loop shown in code segment 2 are contiguous in main memory

Two alloys X and Y contain copper and tin in the ratio 5 : 3 and 7 : 9 respectively. Alloys X and Y are  melted to get an alloy of 48 kg containing copper and Zinc in the ratio  1 : 1. How much percent more alloy Y is used than alloy X to make 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?
