**Answer**: Option B

**Explanation**:

This is a simple division series; each number is one-half of the previous number.

In other terms to say, the number is divided by 2 successively to get the next result.

\(\frac{4}{2}\) = 2

\(\frac{2}{2}\) = 1

\(\frac{1}{2}\) = \(\frac{1}{2}\)

\(\frac {(\frac {1}{2})}{2} \)= \(\frac{1}{4}\)

\(\frac {(\frac {1}{4})}{2} \) =\(\frac{1}{8}\)and so on.

**2. Look at this series: 7, 10, 8, 11, 9, 12, … What number should come next?**

**Clocks & Calendars**:

**1. It was Sunday on Jan 1, 2006. What was the day of the week Jan 1, 2010?**

**Answer**: Option C

**Explanation**:

On 31st December, 2005 it was Saturday.

Number of odd days from the year 2006 to the year 2009 = (1 + 1 + 2 + 1) = 5 days.

On 31st December 2009, it was Thursday.

Thus, on 1st Jan 2010, it is Friday.

**2. What was the day of the week on \(28^{th}\) May 2006?**

**Answer**: Option D

**Explanation**:

\(28^{th}\) May, 2006 = (2005 years + Period from 1.1.2006 to 28.5.2006)

Odd days in 1600 years = 0

Odd days in 400 years = 0

5 years = (4 ordinary years + 1 leap year) = (4 x 1 + 1 x 2) 6 odd days

Jan. Feb. March April May

(31 + 28 + 31 + 30 + 28 ) = 148 days

148 days = (21 weeks + 1 day) 1 odd day.

Total number of odd days = (0 + 0 + 6 + 1) = 7 0 odd day.

Given the day is Sunday.

**3. What was the day of the week on \(17^{th}\)June 1998?**

**Answer**: Option C

**Explanation**:

\(17^{th}\)June, 1998 = (1997 years + Period from 1.1.1998 to 17.6.1998)

Odd days in 1600 years = 0

Odd days in 300 years = (5 x 3) 1

97 years has 24 leap years + 73 ordinary years.

Number of odd days in 97 years ( 24 x 2 + 73) = 121 = 2 odd days.

Jan. Feb. March April May June

(31 + 28 + 31 + 30 + 31 + 17) = 168 days

168 days = 24 weeks = 0 odd day.

Total number of odd days = (0 + 1 + 2 + 0) = 3.

Given the day is Wednesday.

**4. What will be the day of the week \(15^{th}\) August 2010?**

**Answer**: Option C

**Explanation**:

\(15^{th}\) August, 2010 = (2009 years + Period 1.1.2010 to 15.8.2010)

Odd days in 1600 years = 0

Odd days in 400 years = 0

9 years = (2 leap years + 7 ordinary years) = (2 x 2 + 7 x 1) = 11 odd days 4 odd days.

Jan. Feb. March April May June July Aug.

(31 + 28 + 31 + 30 + 31 + 30 + 31 + 15) = 227 days

227 days = (32 weeks + 3 days) 3 odd days.

Total number of odd days = (0 + 0 + 4 + 3) = 7 0 odd days.

Given the day is Sunday.

**5. Today is Monday. After 61 days, it will be:**

**Answer**: Option B

**Explanation**:

Each day of the week is repeated after 7 days.

So, after 63 days, it will be on Monday.

**Problem Solving**:

**1. If one-third of one-fourth of a number is 15, then three-tenths of that number is:**

**Answer**: Option D

**Explanation**:

Let the number be x.

Then,\(\frac{1}{3}\) of \(\frac{1}{3}\) of x= 15

x = 15 x 3 x 4 = 180.

So, required number = (\(\frac{3}{10}\)x 180)= 54.

**2. Three times the first of three consecutive odd integers is 3 more than twice the third. The third integer is:**

**Answer**: Option D

**Explanation**:

Let the three integers be x, x + 2 and x + 4.

Then, 3x = 2(x + 4) + 3

x = 11.

Third integer = x + 4 = 15.

**3. The difference between a two-digit number and the number obtained by interchanging the positions of its digits is 36. What is the difference between the two digits of that number?**

**Answer**: Option B

**Explanation**:

Let the ten’s digit be x and unit’s digit be y.

Then, (10x + y) – (10y + x) = 36

9(x – y) = 36

x – y = 4.

**4. The difference between a two-digit number and the number obtained by interchanging the digits is 36. What is the difference between the sum and the difference of the digits of the number if the ratio between the digits of the number is 1: 2?**

**Answer**: Option B

**Explanation**:

Since the number is greater than the number obtained on reversing the digits, so the ten’s digit is greater than the unit’s digit.

Let ten’s and unit’s digits are 2x and x respectively.

Then, (10 x 2x + x) – (10x + 2x) = 36

9x = 36

x = 4.

Required difference = (2x + x) – (2x – x) = 2x = 8.

**5. A two-digit number is such that the product of the digits is 8. When 18 is added to the number, then the digits are reversed. The number is:**

**Answer**: Option B

**Explanation**:

Let the ten’s and unit digit be x and \(\frac{8}{x}\)respectively.

Then,(10x+\(\frac{8}{x}\)) + 18 = 10*\(\frac{8}{x}\) + x

10\(x^{2}\) + 8 + 18x = 80 + x2

9×2 + 18x – 72 = 0

x2 + 2x – 8 = 0

(x + 4)(x – 2) = 0

x = 2.

**Answer**: Option B

**Explanation**:

Suppose the boy got x sums right and 2x sums wrong.

Then, x + 2x = 48

3x = 48

x = 16.

**2. In a group of cows and hens, the number of legs is 14 more than twice the number of heads. The number of cows is**

**Answer**Option B

**Explanation**:

Let the number of cows be x and the number of hens be y.

Then, 4x + 2y = 2 (x + y) + 14

4x + 2y = 2x + 2y + 14

2x = 14

x = 7.

**3. A father tells his son, “I was of your present age when you were born”. If the father is 36 now, how old was the boy five years back?**

**Answer**Option A

**Explanation**:

Let the father’s age be x and the son’s age be y.

Then, x – y = y or x = 2y,

Now, x = 36. So, 2y = 36 or y = 18.

Therefore Son’s present age = 18 years.

So, son’s age 5 years ago = 13 years.

**4. In a family, a couple has a son and a daughter. The age of the father is three times that of his daughter and the age of the son is half of that of his mother. The wife is 9 years younger to her husband and the brother is seven years older than his sister. What is the age of the mother?**

**Answer**: Option D

**Explanation**:

Let the daughter’s age be x years.

Then, the father’s age = (3x) years.

Mother’s age = (3x – 9) years; Son’s age = (x + 7) years.

So, x + 7 = \(\frac{(3x-9)}{2}\)

2x + 14 = 3x – 9

x = 23.

Therefore Mother’s age = (3X – 9) = (69 – 9)

years = 60 years.

**5. Find the number which when added to itself 13 times, gives 112.**
