If each element in a row of a determinant is multiplied by the same factor r, then the value of the determinant:

If each element in a row of a determinant is multiplied by the same factor r, then the value of the determinant: Correct Answer is multiplied by r

Concept:

If each element of a row (or a column) of a determinant is multiplied by a constant k, then its value gets multiplied by k.

Calculations:

We know that, If each element of a row (or a column) of a determinant is multiplied by a constant k, then its value gets multiplied by k. only

Given , each element in a row of a determinant is multiplied by the same factor r, then its value gets multiplied by r.

There are two rows, each containing 3 numbers. Below are some rules to be used to get the resultant number for each row separately. Use the rule from left to right for each row and find the answer to the question. Rule: 1. If an even number is followed by an even number, then the first number will be subtracted from the second. 2. If an odd number is followed by an odd number, then both will be added. 3. If an odd number is followed by an even number, then the even number will be subtracted from the square of the odd number. 4. If an even number is followed by an odd number, then the odd number will be subtracted from the even number.

Ten people are sitting in two parallel rows 1 and 2. A, B, C, D and E are sitting in row 1 facing north, and V, W, X, Y and Z are sitting in row 2 facing south, in such a way that each member in row 1 faces a member of row 2. A sits second from the right end of the row. W faces an immediate neighbour of A. X sits third to the right of W. The one who faces X, sits to the immediate right of B. Only one person sits between B and C. V sits to the immediate right of Y. D does not sit at any of the extreme ends of the row. Who faces Z?
The digits 1 to 9 are arranged in three rows in such a way that each row contains three digits, and the number formed in the second row is twice the number formed in the first row; and the number formed in the third row is thrice the number formed in the first row. Repetition of digits is not allowed. If only three of the four digits 2, 3, 7 and 9 are allowed to use in the first row, how many such combinations are possible to be arranged in the three rows?
Six friends Ajay, Goarav, Adharav, Saurav, Pari, and Kashvi are sitting in two parallel rows containing three people each. Ajay, Goarav and Adharav are sitting in row-1 facing north and Saurav, Pari and Kashvi are sitting in row-2 facing south (but not necessarily in the same order). Thus, each person sitting in row-1 face another person sitting in row-2. Ajay, Goarav, Saurav and Pari are sitting at extreme ends. Saurav does not face Goarav. Ajay is sitting at extreme right end. Who is sitting at extreme right of row-2?

Consider a 2-dimensional array x with 10 rows and 4 columns, with each element storing a value equivalent to the product of row number and column number. The array is stored in row-major format. If the first element x[0][0] occupies the memory location with address 1000 and each element occupies only one memory location, which all locations (in decimal) will be holding a value of 10?
Eight houses, A, B, C, D, E, F, G and H, are in two parallel rows, I and II, with 4 houses in each row. The houses in each row are at equal distances. The four houses in row-I are facing north, and are facing the four houses in row-II. B in row-I faces F and is not at an extreme end. H is adjacent to F and is facing D. C and E are diagonally opposite. E is facing A, who is adjacent to H. Which of the following statements is true?
The first row of a certain determinant has the numbers 3 and 5. The second row has the numbers 7 and 2. The value of this determinant is
Six people are sitting in two parallel rows containing three people each, in such a way that there is an equal distance between adjacent persons. In row 1, P, S and T are sitting (but not necessarily in the same order) and all of them are facing South. In row 2, U, Q and R are sitting (but not necessarily in the same order) and all of them are facing North. Therefore, in the given seating arrangement each member seated in a row faces another member of the other row. U sits in the extreme left end position and faces P. S sits in the middle and doesn’t face R. Who amongest the following faces T?
