Let the monthly income of Rohan be Rs. 350x.
Since Sohan’s income is (75/3)% = 25% more than Rohan’s income:
Now, the required percentage decrease:
I. 6p2 – 7p = 5p – 7p2 + 25
II. 11q2 – 63q + 90 = 0
I. 6x2 – 7x - 20 = 0
II. 3y2 - y - 14 = 0
I. x2 + (9x/2) + (7/2) = - (3/2)
II. y2 + 16y + 63 = 0
I. 8a2 – 22a+ 15 = 0
II. 12b2 - 47b + 40=0
Solve the quadratic equations and determine the relation between x and y:
Equation 1: x² - 24x + 135 = 0
Equation 2: y² - 26y + 153 = 0
I. x2 + 28x + 96 = 0
II. y2 + 3y - 70 = 0
Solve both equations I & II and form a new equation III in variable ‘r’ (reduce to lowest possible factor) using roots of equation I and II as per ...
I. 7x² + 27x + 18 = 0
II. 19y² - 27y + 8 = 0
I. 3p2 - 11p + 10 = 0
II. 42q2 + q -1 = 0
I. 7x + 8y = 36
II. 3x + 4y = 14
