Now as per the given statements,
x – y = 800 .....(1) 120%y = x - 20 %y y = 5x/7 ------(2)
Using (3) to solve (1) we get x - 5x/7 = 800 2x/7 = 800 x = 2800,y = 2000 Now, we know that A & B collectively won 80% of total votes. If the total number of registered voters in the village be M,
80 %M = 2800 + 2000 = 4800 so, M = 4800/80 % = 6000
I. 4x2 + 9x - 9 = 0
II. 4y2 - 19y + 12 = 0
I. x2 - 20x + 96 = 0
II. y2 - 23y + 22 = 0
I. p2 – 2p – 15 = 0
II. q2 + 4q – 12 = 0
I. 4x2 – 53x – 105 = 0
II. 3y2 – 25y + 48 = 0
I. 14p² + 9p - 8 = 0
II. 4q² - 19q + 12 = 0
I. 104x² + 9x - 35 = 0
