Q1. A is twice as efficient as B. Both can complete a work together in  days. Quantity 1: Time taken by B to complete the work alone. 
Quantity 2: If C is 50% more efficient than A, then time taken by C to complete the work alone.

Quantity I > Quantity II

Quantity I ≥ Quantity II

Quantity II > Quantity I

Quantity II ≥ Quantity I

Quantity I = Quantity II or Relation cannot be established

Solution:

Q2. One of the roots of 2x² + bx - 5 = 0 is 1. 
Quantity 1: Value of the other root. 
Quantity 2: 2.5

Quantity I > Quantity II

Quantity I ≥ Quantity II

Quantity II > Quantity I

Quantity II ≥ Quantity I

Quantity I = Quantity II or Relation cannot be established

Solution:

Q3. Two dices are rolled simultaneously. 
Quantity 1: Probability that the sum of the numbers that appeared is a multiple of 5. 
Quantity 2: 1/6

Quantity I > Quantity II

Quantity I ≥ Quantity II

Quantity II > Quantity I

Quantity II ≥ Quantity I

Quantity I = Quantity II or Relation cannot be established

Solution:

From I,
Fovorable cases
= (1,4),(2,3),(3,2),(4,1),(5,5),(4,6),(6,4)
= 7
∴ Required prob. =7/36
From II, Quantity II =1/6
Quantity I > Quantity II

Q4. In a match of 50 overs, team A’s average runs for first thirty overs was 4.5 runs/over while for the remaining 20 overs the average was 5.5 runs/over. Team B chased the target and lost by 10 runs. Find the average runs per over scored by team B. (team B played all the 50 overs).

Solution:

Total runs scored by team B = 30 × 4.5 + 20 × 5.5 - 10
= 235
∴ Required answer = 235/50
= 4.7

Solution:

Directions (6-10): In each of these questions, two equations numbered I and II are given. You have to solve both the equation and give answer 

Q6. I. 2x² +11x+15=0 
II. 4y²+13y+9=0

if x < y

if x ≤ y

if x > y

if x ≥ y

if x = y or the relationship cannot be established

Solution:

Q7. I. x²-36x+324=0 
II. y²-35y+216=0

if x < y

if x ≤ y

if x > y

if x ≥ y

if x = y or the relationship cannot be established

Solution:

Q8.

if x < y

if x ≤ y

if x > y

if x ≥ y

if x = y or the relationship cannot be established

Solution:

Q9. I. 2x² + 17x + 35 = 0 
II. 3y² + 17y + 24 = 0

if x < y

if x ≤ y

if x > y

if x ≥ y

if x = y or the relationship cannot be established

Solution:

I. 2x² + 17x + 35 = 0
2x² + 10x+ 7x + 35 = 0
2x (x+ 5) +7 (x+ 5) = 0
(2x+ 7) (x+ 5) =0
x = (-7)/2, -5
II. 3y² + 17y + 24 = 0
3y² + 9y + 8y + 24 = 0
3y (y + 3) + 8 (y+ 3) = 0
(y+ 3) (3y + 8) = 0
y= -3, -8/3
y > x

Q10. I. x² + 72 = 108 
II. y³ + 581 = 365

if x < y

if x ≤ y

if x > y

if x ≥ y

if x = y or the relationship cannot be established

Solution:

I. x² + 72 = 108
x² =108 – 72 = 36
x = ±6
II. y³ + 581 = 365
y³ = –216
y = –6
x ≥ y
