What is the average salary of 10 officers , if a clerk’s salary is Rs. 15,000?

The quadratic equation 2x² − kx + 3 = 0 has equal roots. Find k.

If x^2 - 7x + k = 0 has roots that are equal, what is the value of k?

Solve the quadratic equations and determine the relation between x and y:

Equation 1: x² - 22x + 120 = 0

Equation 2: y² - 25y + 144 = 0

I). 4p + 3q = 25

II). 5p + 2q = 26 

I. x² + 28x + 96 = 0

II. y² + 3y - 70 = 0

I. 5q = 7p + 21

II. 11q + 4p + 109 = 0
