Explanation

The consistent rule that gives both is: +1, +1, +1, +1, +2, +2 

F +1 = G  

U +1 = V  

T +1 = U  

U +1 = V  

R +2 = T  

E +2 = G  

Now apply the same to HONEST:  

H +1 = I  

O +1 = P  

N +1 = O  

E +1 = F  

S +2 = U  

T +2 = V  

So HONEST = IPOFUV

Explanation

• Einstein's mass-energy equivalence equation is E = mc².
• E represents energy, m represents mass, and c represents the speed of light in a vacuum.
• The equation shows that mass can be converted into energy and energy into mass.

Explanation

• Ohm's law, description of the relationship between current, voltage, and resistance.
• Georg Simon Ohm stated that the electric current through a conductor is directly proportional to the voltage across it, provided temperature remains constant. 
• This relationship is called Ohm’s Law.

Explanation

• Frequency is the number of occurrences of a repeating event per unit of time.
• The SI unit of frequency is the hertz (Hz).
• 1 Hz = 1 cycle or vibration per second
• Unit: Hz = s⁻¹ (per second)
• Named after physicist Heinrich Hertz
• Used for waves, oscillations, sound, and electromagnetic radiation
• Derivations from other quantities: f = 1 / T
• Dimension T^−1

Explanation

• Since all laptops are computers and no computer is a mobile phone, no laptop can be a mobile phone.
• This conclusion follows directly from the given statements.

Let's check the pattern for FEDERAL → GFEFSBM

F E D E R A L  

G F E F S B M  

Compare each letter:

F + 1 = G  

E + 1 = F  

D + 1 = E  

E + 1 = F  

R + 1 = S  

A + 1 = B  

L + 1 = M  

Pattern: Each letter is moved 1 step forward in the alphabet

Now apply to AGENCY:  

A + 1 = B  

G + 1 = H  

E + 1 = F  

N + 1 = O  

C + 1 = D  

Y + 1 = Z  

So AGENCY = BHFODZ

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 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

Given: SCHOOL = TDIPPM

Check letter by letter:

S -> T = +1  

C -> D = +1  

H -> I = +1  

O -> P = +1  

O -> P = +1  

L -> M = +1  

Pattern: Each letter is increased by 1

Now code for BOOK:

B -> C  

O -> P  

O -> P  

K -> L  

Code = CPPL

Explanation

Net north = 10 − 6 = 4 km

East = 3 km

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