# Quantitative Section : Quantitative Comparision

In this section there are two quantities. You need to determine the relation between the two quantities.

1. a < 3 and b > 3
Quantity 1: ba
Quantity 2: ab
1. Both the quantities are equal
2. 1 is less than 2
3. 2 is less than 1
4. No relation

Ans : A

Explanation:
ab = ba, therefore (a) is the correct answer.

2. Quantity 1: (-9)8
Quantity 2: (-9)2
1. Quantity 1 is greater than Quantity 2
2. Quantity 2 is greater than Quantity 1
3. Both the quantities are equal
4. There is no relationship between the two quantities

Ans : A

Explanation:
(-9) 8 = -72 while (-9) 2= -81,
Therefore (a) is the right answer

3. a2 + b2 = (14) 2 and ab = 27
Quantity 1: a2 + 2ab+ b2
Quantity 2: (a + b) 2
1. Quantity 2 is greater than quantity 1
2. There is no relation between both the quantities
3. Quantity 1 is equal to Quantity 2
4. Quantity 1 is greater than Quantity 2

Ans : C

Explanation:
(a + b) 2 = a2 + 2ab+ b2, therefore option (c) is the right answer

4. 11 > a < 35, while 25 > b < 55
Quantity 1: a
Quantity 2: b
1. Value of quantity 2 is more than value of quantity 1
2. Value of quantity 1 is more than value of quantity 2
3. Values of both quantity 1 and 2 are equal
4. There is no relation between the 2 quantities

Ans : D

5. Quantity A: (1/30)1/2 + (1/1089) 1/2
Quantity B: (1/55) + (1/35)
1. Quantity A is smaller than Quantity B
2. There is no relation between both the quantities
3. Quantity B is smaller than Quantity A
4. Quantity A = Quantity B

Ans : B

Explanation:
Quantity A is the square root followed by division, where as quantity B is just division, hence no relation.

6. a + b = 20
Quantity 1: 20
Quantity 2: a – b
1. Quantity 1 is equal to Quantity 2
2. Quantity 2 is greater than Quantity 1
3. No relation
4. Quantity 1 is greater than Quantity 2

Ans : C

Explanation:
As quantity 1 is 20 = a + b and quantity 2 is a – b, option (c) is the right answer

7. x is a negative integer
5/20 = x/y
Quantity 1: x/y
Quantity 2: 2
1. Quantity 2 is less than Quantity 1
2. Quantity 1 is less than Quantity 2
3. Quantity 1 is equal to Quantity 2
4. No relation

Ans : D

Explanation:
5/20 = x/y
1/2 = x/y
Therefore there is no relation between 1 and 2

8. Both Tom and David started from the same point and covered a distance of 150 miles. Tom is driving at the speed of 50 miles per hour, while David is driving at the speed of 45 miles per hour. Determine who reached first.
1. Tom came first
2. Both reached at the same time
3. Mike reached first
4. No relation

Ans : C

Explanation:
Tom is driving at the speed of 50 miles per hour so he reaches in 4 hours, while David is driving at a speed of 45 miles per hour, so he reaches in 2.5 hours; hence (c) is the correct answer

9. Quantity 1: (-5) 8
Quantity 2: (-5) 2
1. Quantity 1 is greater than Quantity 2
2. Quantity 2 is greater than Quantity 1
3. Both the quantities are equal
4. There is no relationship between the two quantities

Ans : A

Explanation:
(-5) 8 = -40 while (-5) 2= -25,
Therefore (a) is the right answer

10. Quantity 1: 7/126
Quantity 2: 0.35/9
1. Quantity 1 is greater than Quantity 2
2. Quantity 2 is greater than Quantity 1
3. There is no relation between both the quantities
4. Both the quantities are equal

Ans : B

Explanation:
7/126 = 0.05; 0.35/9 = 0.38
