Quant Test 17 1. Nangru is standing on a point X such that the point X lies on the first quadrant of a Cartesian Co-ordinate system. After travelling to five different points in the first quadrant, he came back to the point X. The ‘x’ and ‘y’ co-ordinates of each point to which he traveled is a prime number. What is the minimum possible area of the region enclosed by Nangru? Assume that during the course of his travel he neither retraced nor crossed the path through which he has already traveled once. Also, the distance between the two consecutive points which he had traveled is an integer.

3. In a survey conducted on the usage of mobile phones namely Nokia, Samsung and Motorola, it was found that 50 people use Motorola and 34 people use both Nokia and Motorola. How many people are there who use both Nokia and Samsung but do not use Motorola? A: The number of people who use both Nokia and Samsung but do not use Motorola is twice the number of people using both Samsung and Motorola. The number of people using all the three mentioned mobile phones is 10 less than the number of people who use only Motorola. B: Out of the number of people surveyed, the number of people using all the three mentioned mobile phones is 3.

There is a N × N square matrix having N2 cells of dimension 1 × 1. Every cell in the matrix is given an address (i, j), where (i, j = n, n + 1, ……) and n is an integer. It is given that one of the box is marked as (0, 0). Every other cell is given an address (i, j) as per the Cartesian coordinate system. All addresses are given with reference to the central most cell (0, 0). For example, the cell to the immediate right of (0, 0) along the same row is given an address (1, 0). Similarly, the cell above (0, 0) along the same column is given an address (0, 1).

8. If the addresses of the cells sharing a common point or a common boundary with the cell having the address (i, j) are (i1, j1)....(im, jm) , then what is the value of |(i – i1)| + ……. |(i – im)|? (1) 2 (2) 3 (3) 6 (4) Either 2 or 3 (5) Either 2 or 3 or 6
