Consider the following statements: A characteristic of the structure of metallic atoms is that 1. their outermost orbital of electrons is nearly complete and they attract electrons from other atoms 2. their atoms are smaller and more compact than those of non-metallic elements Which of the above statements is/are correct? Correct Answer Neither 1 and 2

The tendency of an atom to lose one more valance electrons to form positive ion is known as metallic character. These atoms are considered as metal. Therefore the metals have the tendency to lose the atoms.

Metallic character increase with increase in the size of atom. This is due to the fact that greater the size of atom, the farther is the valence electron from the nucleus and lesser is the pull exerted on it. As a result electrons can be removed more easily from the valence shell, thus making the elements, more metallic. Therefore the metallic elements have more size of the atoms compared to their non-metallic counterparts.

Note:

The tendency of an atom to gain electron and form negative ion is known as non-metallic character and those atoms are considered as non-metals.

The non-metallic character increases with decrease in size of the atom. The smaller the size of atom greater is the nuclear attraction on valance electrons and hence the more non-metallic the element.

The question given below consists of a statement, followed by three arguments I, II and III. You have to decide which of the arguments is/are ‘strong’ arguments is/are ‘weak’ arguments and accordingly choose your answer from the alternatives given below each question. Statement: India's burgeoning shadow finance sector is likely to face a shake-up after defaults at one major lender battered the nation's financial markets in the past week and reinforced worries about credit risk. Industry officials and experts say they expect Indian regulators to cancel the licences of as many as 1,500 smaller non-banking finance companies because they don't have adequate capital, and to also make it more difficult for new applicants to get approval. Which of the following argument(s) stated support(s) the given fact? Arguments: I. Better capitalised and more conservatively run finance firms are likely to swallow up an increasing number of smaller rivals. That could make it difficult for many small borrowers to get loans, especially in the countryside where two-thirds of India's 1.3 billion people live and put the brakes on a surge in private consumption with a knock-on effect on growth.  II. The shadow banking sector now comprises more than 11,400 firms with a combined balance-sheet worth 22.1 trillion rupees ($304 billion) and is less strictly regulated than banks. It has been attracting new investors, particularly as the nation's banks have had to slow their lending as they seek to work through $150 billion of stressed assets.  III. Nearly 11,000 of India's NBFCs are small and medium-sized businesses with an asset base of less than 5 billion rupees. But the top 400, many of which are backed by banks and finance companies, control about 90 percent of the assets under management.
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
