## Aptitude Algebraic Expressions Test Paper 11) If x - 3
- 4
- 5
- None of these
Adding 2 to the L.H.S and R.H.S of the equation: x (x+) (x+)= +6,-6 2) The value of x in the equation: 16x += 8 is
16x+=8 =8 16x =>16x =>(4x-1) =>x = 3) The equation whose roots are 4 and 5, is - x
^{2}+9x-20=0 - x
^{2}+9x+20=0 - x
^{2}-9x+20=0 - x
^{2}-9x-20=0
The required equation is: 4) The perimeter of a rectangle is 48 meters, and its area is 135 m2. The sides of the rectangle are - 15 m, 9m.
- 19m, 5m.
- 45m, 3m.
- 27m, 5m.
Let the sides of the rectangle be x and y meters respectively. Then We have, xy = 135 5) The roots of the equation (x + 3) (x - 3) = 160 are __+__13- 13, 13
__+__12- 12, 12
(x + 3) (x - 3) = 160 Aptitude Algebraic Expressions Test Paper 2 Aptitude Algebraic Expressions Test Paper 3 Aptitude Algebraic Expressions Test Paper 4 |
