Q 1 - If the average of two consecutive even numbers is 27, what are those numbers?

### Answer : D

### Explanation

**Step 1:**

Let the consecutive even numbers be n and n+2

Their average is (n + n + 2)/2 = (2n + 2)/2 = 27

(2n + 2) = 27 × 2 = 54

2n = 54 – 2 = 52; n = 52/2 =26

**Step 2:**

So the consecutive even numbers are 26 and 26 + 2 or 26 and 28

Q 2 - If the average of two consecutive natural numbers is 44.5, what are those numbers?

### Answer : A

### Explanation

**Step 1:**

Let the consecutive natural numbers be n and n+1

Their average is (n + n + 1)/2 = (2n + 1)/2 = 44.5

(2n + 1) = 44.5 × 2 = 89

2n = 89 – 1 = 88; n = 88/2 = 44

**Step 2:**

So the consecutive natural numbers are 44 and 44+1 or 44 and 45

### Answer : C

### Explanation

**Step 1:**

Cube of 3 = 33 = 27

Cube of 6 = 63 = 216

**Step 2:**

Average of cubes of 3 and 6 = (27 + 216)/2 = 243/2 = 121.5

### Answer : B

### Explanation

**Step 1:**

The average of 19 and q = (19 + q)/2 = 27

19 + q = 27 × 2 = 54

q = 54 – 19 = 35

**Step 2:**

So, q = 35

### Answer : C

### Explanation

**Step 1:**

The first two odd prime numbers are 3 and 5

**Step 2:**

Their average = (3 +5)/2 = 8/2 = 4

### Answer : A

Q 8 - If the average of two consecutive whole numbers is 29.5, what are the numbers?

### Answer : B

### Explanation

**Step 1:**

Let the consecutive natural numbers be n and n+1

Their average is (n + n + 1)/2 = (2n + 1)/2 = 29.5

(2n + 1) = 29.5 × 2 = 59

2n = 59 – 1 = 58; n = 58/2 = 29

**Step 2:**

So the consecutive natural numbers are 29 and 29+1 or 29 and 30

### Answer : A

### Explanation

**Step 1:**

The average of 28 and q = (28 + q)/2 = 21

28 + q = 21 × 2 = 42

q = 42 – 28 = 14

**Step 2:**

So, q = 14

### Answer : B

### Explanation

**Step 1:**

The average of 48 and p = (48 + p)/2 = 42.5

48 + p = 42.5 × 2 = 85

p = 85 – 48 = 37

**Step 2:**

So, p = 37
