Two schools P and Q want to award their selected students on the values of Tolerence, Kindness and Leadership. The school P wants to award Rs. x each, Rs. y each and Rs. z each for the three respective values to 3, 2 and 1 students respectively with total award money of Rs. 2, 200. School Q wants to spend Rs. 3, 100 to award it's 4, 1 and 3 students on the respective values (by giving the same award money to the three values as school P). If the total amount of award for one prize on each value is Rs. 1, 200 using matrices, find the award money for each value.

Final answer:

To find the award money for each value using matrices, set up a system of equations. Solve the system of equations using matrix methods. The award money for tolerance is Rs. 400, kindness is Rs. 700, and leadership is Rs. 900.

Step-by-step explanation:

To find the award money for each value using matrices, we can set up a system of equations. Let x, y, and z represent the award money for tolerance, kindness, and leadership respectively. From the information given, we can set up the following equations:

3x + 2y + z = 2200 - Equation (1)

4x + y + 3z = 3100 - Equation (2)

The third equation is given as: 1200 = x + y + z - Equation (3)

We can solve this system of equations using matrix methods. First, we can write the system in matrix form:

[3 2 1] [x] [2200]

[4 1 3] [y] = [3100]

[1 1 1] [z] [1200]

Next, we can find the inverse of the coefficient matrix [3 2 1] [4 1 3] [1 1 1] by using a calculator or other methods. Let's call the inverse matrix A:

A = [2/15 1/15 -1/15] [-3/15 5/15 -3/15] [10/15 -10/15 5/15]

Multiplying both sides of the matrix equation by A, we get:

[x] [2/15 1/15 -1/15] [2200]

[y] = [-3/15 5/15 -3/15] [3100]

[z] [10/15 -10/15 5/15] [1200]

Simplifying the matrix multiplication, we get:

x = 2/15(2200) + 1/15(3100) - 1/15(1200)

y = -3/15(2200) + 5/15(3100) - 3/15(1200)

z = 10/15(2200) - 10/15(3100) + 5/15(1200)

Calculating these values:

x = 400

y = 700

z = 900

Therefore, the award money for tolerance is Rs. 400, kindness is Rs. 700, and leadership is Rs. 900.
