B) The car covers a distance 210 km in 7 hours.

6. If 6x^2 + 5x + 1 < 0 then the value of x satisfies which inequality are?
A.  -1/2 < x < -1/3
B.   x < -1/2 and x > -1/3
C.   x  -1/2
D.   x  1/2
E.   None of these

Directions (Q. 7-8): In each of these questions, two equations I and II with variable ‘x’ and ‘y’ are given. You have to solve both the equations to find the value x and y and give answer:

A.  If x < y 
B.   If x   y 
C.   If x = y 
D.   If x  y 
E.   If x > y

7. 
I. x^2 = 9 
II. y^2 + 8y + 16 = 0

8. 
I. 4x^2 + 10x – 6 = 0 
II. y^2 – 5y + 6 = 0

9. The radius of a copper sphere is 6 cm. The sphere is melted and drawn into a long wire of uniform circular cross section. If the length of the wire is 72 cm, then the radius of wire is ?
A.   4 cm 
B.   4.2 cm 
C.   2 cm 
D.   3 cm 
E.   None of these

10. The ratio of length of rhombus is 3 : 4. Then, the ratio of the area of the rhombus to the square of the shorter diagonal is?
A.   3 : 2 
B.   3 : 8 
C.   1 : 2 
D.   4 : 3 
E.   None of these

Answers:
1. D
Using statements A
Profit % = (5 - D.  /4 * 100 = 25%
Cost price = 125 * 100/125 = Rs. 96
Profit = 120 – 96 = Rs. 24
Similarly, we can find profit by using statement B.

2. E
From statement A salary of C = 2.5 B
From statement B, A + B = 2 × 4000 = Rs. 8000

3. B
From statement B, radius of circle = sq. root (169) m = 13m
Required area = π r^2
= 22/7 * (1C.  ^2

4. A
From statement A, 3/5 * x = x - 90
2/5x = 90

From B, x/4 = x/4 we can't determine the value of x

5. D
Since, speed of car = Distance covered by it/ Time taken by it

6. A
5x^2 + 6x + 1 < 0
6x^2 + 3x + 2x + 1 < 0
(2x + A.  (3x + A.  < 0
(x + 1/B.   (x + 1/C.   <0
- 1/2 < x < -1/3

7. E
From equation I:
x^2 = 9
x = +/-3
From II:
y^2 + 8y + (D.  ^2 = 0
(y + D.  ^2 = 0
y = - 4
x > y

8. A
I: 4x^2 + 12x - 2x - 6 = 0
4x (x + C.   - 2 (x + C.   = 0
(4x - B.   ( x + C.   = 0
x = -3 or 1/2


II:
y^2 - 5y + 6 = 0
(y -C.  (y - B.   = 0
y = 3 or 2
y > x

9. C
___r^2 * 72 = 4/3 π  * (6)^3
r^2 = 4
r = 2 cm

10. E
Area of rhombus = 1/2 * 3x * 4x = 6x^2
Square of the shorter diagonal = 3x^2 = 9x^2
Req. Ratio = 6x^2/9x^2 = 2/3
