Question
PC Mahalanobis is remembered as a major contributor of
India’s developmental path because he __________. (A)set up Indian Institutes of Management located in different parts of India (B)formulated the Second Five-Year Plan (C)was the first Minister of Statistics and Programme ImplementationSolution
The correct answer is D
I. 4x2 + 3√7 x-7 =0
II. 7y2 + 4√7 y-5=0
I. 5x2 – 7x – 6 =0
II. 2y2 – 5y – 7 =0
I. 6x2 - 47x + 77 =0
II. 6y2 - 35y + 49 = 0
Solve: x² − 7x + 12 = 0
I. 2b2 + 31b + 99 = 0
II. 4a2 + 8a - 45 = 0
I. p² - 10p +21 = 0
II. q² + q -12 = 0
I. 2x² + 11x + 12 = 0
II. 2y² + 19y + 45 = 0
Solve the quadratic equations and determine the relation between x and y:
Equation 1: 19x² - 92x + 73 = 0
Equation 2: 17y² - 76y + 59 = 0
I. 6 y² + 11 y – 7= 0
II. 21 x² + 5 x – 6 = 0
- If the quadratic equation x² + 18x + n = 0 has real and equal roots, what is the value of n?
