## Question:

### There are 7 numbers in the set and all the numbers are distinct integers. What is the median of these 7 numbers, when they are arranged in an ascending order?

(1) Median of the first five numbers is 11

(2) Median of the last five numbers is 13

#### Option Choices:

A. Statement (1) ALONE is sufficient, but Statement (2) alone is not sufficient.

B. Statement (2) ALONE is sufficient, but Statement (1) alone is not sufficient.

C. Both statement TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.

D. Each statement ALONE is sufficient.

E. Statement (1) and (2) TOGETHER are not sufficient.

## Solution :

### Step 1: Analyse Question Stem

• It’s given that all the numbers are distinct integers
• We need to find, what is the median of the 7 numbers, when all of them are arrange in an ascending order.
• Let’s assume the numbers as N1, N2, N3, N4, N5, N6, and N7
• Where N1 < N2 < N3 < N4 < N5 < N6 < N7
• The median in this case is N4.

### Step 2: Analyse Statements Independently (And eliminate options) – AD/BCE

#### Statement 1: Median of first five numbers is 11

Here the median of 7 numbers is N4 but we can’t infer anything about N4 from this statement.

Hence, statement 1 alone is not sufficient. We can eliminate answer option A and D.

#### Statement 2: Median of last five numbers is 5

Here also we cannot infer anything about number N4.

Hence, statement 2 also not sufficient. We can eliminate option B

### Step 3: Analyse Statements by Combining

From statement 1:

N3 = 11

Frome statement 2:

N5=13

After combining the 2, we get

Since, all the numbers are distinct integers and arranged in ascending order, N4 must be 12.

Thus, the median is 12 and the correct answer is option C
