Magic Square Arrange the numbers from 1 to 25 in a 5X5 matrix, with each number occurring exactly once such that the sum of the entries of any row, any column, or any main diagonal is the same. Hint: Total sum will be 65

Sitting Arrangement Eight people, E, F,G, H, J, K, L, and M are sitting around a circular table facing the centre. Each of them is of a different professions: Chartered Accountant, Columnist, Doctor, Engineer, Financial Analyst, Lawyer, Professor, and Scientist but not necessarily in the same order. F is sitting second to the left of K. The Scientist is an immediate neighbor of K. There are only three people between the Scientist and E. Only one person sits between the Engineer and E. The columnist is to the immediate right of the Engineer. M is second to the right of K. H is the Scientist. G and J are immediate neighbors of each other. Neither G nor J is an Engineer. The Financial analyst is to the immediate left of F. The lawyer is second to the right of the Columnist. The Professor is an immediate neighbor of the Engineer. G is second to the right of the Chartered Accountant. Draw a diagram showing who is sitting where.

E: Chartered Accountant L: Engineer M: Columnist K: Professor H: Scientist F: Doctor G: Financial Analyst J: Lawyer
