Linear Equation
If ( a + 1/a )2 = 3, then the value of a3 + 1/a3 is

a) 0
b) 9
c) 3&?#8804;3
d) &?#8804;3



Answer
Solution
Correct Answer Is : 0
Solution Is : ( a + 1/a )2 = 3 a + 1/a = &?#8804;3 on cubing, a3 + 1/a3 + 3 ( a + 1/a ) = 3&?#8804;3 => a3 + 1/a3 + 3&?#8804;3 =3&?#8804;3 => a3 + 1/a3 = 0
If X2 - 6X + 1 = 0, then X2 + 1/X2 =

a) 0
b) 3
c) 4
d) 34



Answer
Solution
Correct Answer Is : 34
Solution Is : X2 - 6X + 1 = 0 => X2 - 1 = 6X => X + 1/X = 6 On squaring, X2 + 1/X2 + 2 = 36 => X2 + 1/X2 = 36 - 2 = 34.
Among the equations x+2y+9 =0; 5x-4=0; 2y-13=0;2x-3y=0, the equation o the straight line passing through origin is

a) 2x-3y=0
b) 5x-4=0
c) X+2y+9=0
d) 2y-13=0



Answer
Solution
Correct Answer Is : 2x-3y=0
Solution Is : 2x - 3y = 0 is passing through origin because its satisfy x = 0 and y = 0.
If x = 2 then the value of x3 + 27x2 + 243x + 631 is

a) 1233
b) 1231
c) 1321
d) 1211



Answer
Solution
Correct Answer Is : 1233
Solution Is : Given x = 2
then x3 + 27x2 + 243x + 631
= 8 + 108 + 486 + 631
= 1233
If x: y = 4 : 5, then (3x + y) (5x + 3y) =

a) 3:05
b) 5:03
c) 17:35
d) 01-01-00 11:17



Answer
Solution
Correct Answer Is : 17:35
Solution Is : X/y = 4/5. We know that x = 4 and y = 5. That`s how we got the ratio (x/y) or (4/5) Just substitute the values of x&y in the other ratio with unknowns.
(3x + y):(5x + 3y)
[3(4) + 5]:[5(4) + 3(5)]
17:35

a) 730/77
b) 73/77
c) 73/770
d) 74/77



Answer
Solution
Correct Answer Is : 73/77
Solution Is :

Answer
Solution
Correct Answer Is : 12098
Solution Is :

Answer
Solution
Correct Answer Is : 4
Solution Is :
If x2 - 3x + 1 = 0, then the value of x6 + x4 + x2 + 1/ x3 will be

a) 18
b) 15
c) 21
d) 30



Answer
Solution
Correct Answer Is : 21
Solution Is :
If x4 + 1/x4 = 119 and x > 1, then find the positive value of x3 - 1/x3

a) 25
b) 27
