Explanation

Net north = 10 − 6 = 4 km

East = 3 km

Distance from starting point = √(4² + 3²) = √25 = 5 km

Explanation

Let's stack them from top to bottom:

1. Green box is above the blue box

2. White box is below the green box 

3. Red box is between the green box and the white box

So the order is:  

Green

Red ← between green and white  

White

Blue ← below green

The blue box is at the bottom.

Explanation

Step 1: Go 40 km North

Step 2: Turn left and go 40 km West  

Step 3: Turn right and go 30 km North

Now make coordinates:

Starting point = (0, 0)

After step 1 = (0, 40)

After step 2 = (-40, 40) 

After step 3 = (-40, 70)

Distance from start to end = sqrt[ (x)^2 + (y)^2 ]

= sqrt[ (-40)^2 + (70)^2 ]

= sqrt[ 1600 + 4900 ]

= sqrt[ 6500 ]

= 80.62 km

Approx distance = 80.6 km

Explanation

Given: P = False, Q = True, R = False

Expression: (~P ∧ Q) ∨ R

1. ~P = ~False = True

2. ~P ∧ Q = True ∧ True = True

3. (~P ∧ Q) ∨ R = True ∨ False = True

------

Quick Rule

NOT changes the value.

AND is True only when both are True.

OR is True when at least one is True.

Explanation

Let's check with Venn diagrams:

Statements:

1. All investigators are trained officers. → Investigators ⊂ Trained Officers

2. Some trained officers are lawyers. → Trained Officers ∩ Lawyers ≠ ∅

3. No lawyer is an accountant. → Lawyers ∩ Accountants = ∅

Conclusions:

I. Some investigators are lawyers.

We know investigators are trained officers, and some trained officers are lawyers. But we don't know if those "some" overlap with investigators.  

→ Does not follow

II. No investigator is an accountant.  

We know no lawyer is an accountant. But we don't know if investigators are lawyers. Investigators could still be accountants since we have no direct link between investigators and accountants.  

→ Does not follow

III. Some trained officers are not accountants.

Some trained officers are lawyers. And no lawyer is an accountant.  

So those trained officers who are lawyers cannot be accountants.  

→ Follows

Answer: Only III follows

Let's arrange them by age using the clues:

1. Ali is older than Babar but younger than Danish

   → Danish > Ali > Babar

2. Hamza is younger than Babar  

   → Danish > Ali > Babar > Hamza

3. Kashif is older than Danish

   → Kashif > Danish > Ali > Babar > Hamza

Full order from oldest to youngest:  

Kashif > Danish > Ali > Babar > Hamza

The second-oldest is Danish.

Let's check each team against the rules:

Rules:

1. If A is selected → B must also be selected

2. C and D cannot be together  

3. At least one of D or E must be selected

4. B and E cannot be together

B, C, D  

Rule 2: C and D are together → Fails

B, C, E

Rule 4: B and E are together → Fails

A, B, D  

1. A is selected, B is selected → OK  

2. C and D not together → OK  

3. D is selected → OK  

4. B and E not together → OK

Explanation

Let's match the words to codes:

1. “Police investigate crime” = na ki lo

2. “Crime affects society” = lo pa se

3. “Police protect society” = na tu se

Compare 1 and 2:  

Common words: crime

Common code: lo  

→ crime = lo

Compare 1 and 3:  

Common words: police  

Common code: na

→ police = na

Compare 2 and 3:  

Common words: society  

Common code: se

→ society = se

Now in sentence 3: “Police protect society” = na tu se  

We have: police = na, society = se  

So the remaining word protect = tu

Explanation

Let's make a table:

Departments: Cybercrime, Immigration, Anti-Corruption, Administration  

Officers: Aslam, Danish, Farhan, Junaid

Clues:

1. Danish = Immigration

2. Aslam ≠ Cybercrime, Aslam ≠ Administration

3. Farhan ≠ Administration

4. Junaid ≠ Cybercrime

From clue 1: Danish takes Immigration.  

Left: Cybercrime, Anti-Corruption, Administration for Aslam, Farhan, Junaid

From clue 2: Aslam ≠ Cybercrime, Aslam ≠ Administration → Aslam = Anti-Corruption

Left: Cybercrime, Administration for Farhan, Junaid

From clue 3: Farhan ≠ Administration → Farhan = Cybercrime

Left: Junaid = Administration

Final assignment:

Aslam: Anti-Corruption

Danish: Immigration  

Farhan: Cybercrime

Junaid: Administration

Explanation

Let's track Ahmed's movement:

Start at origin, facing North

1. Walks 8 km North → Now 8 km North of start

2. Turns Right → Now facing East. Walks 6 km East

3. Turns Right → Now facing South. Walks 8 km South  

   This brings him back to the same North-South line as start. Net: 8N - 8S = 0

4. Turns Left → Was facing South, left = East. Walks 3 km East

Final position:  

North-South: 0 km from start  

East-West: 6 km + 3 km = 9 km East of start
