A survey shows: 65% of tobacco users were advised to stop. Also, 3 out of 10 tobacco users attempted to stop. Based only on this data, which statement can be inferred with certainty?
Show Hint
- A majority of tobacco users who were advised to stop consuming tobacco made an attempt to do so.
- A majority of tobacco users who were advised to stop consuming tobacco did not attempt to do so.
- Approximately 30% of tobacco users successfully stopped consuming tobacco.
- Approximately 65% of tobacco users successfully stopped consuming tobacco.
The Correct Option is B
Solution and Explanation
Step 1: Translate the information.
- \(65%\) of users were advised to quit.
- Only \(30%\) (3 out of 10) attempted quitting.
Step 2: Link the groups.
All attempts (30%) must come from the "advised" group (65%), because only those advised can be expected to attempt.
So, among those advised (65%), only 30% attempted.
Step 3: Majority check.
Since 65% were advised but only 30% attempted, the remainder (35%) did not attempt.
Thus, within the advised group, more than half did not attempt quitting.
Step 4: Eliminate wrong options.
(A) Claims majority of advised did attempt — false.
(C) and (D) talk about successfully quitting, but success data is not given — cannot infer.
Only (B) follows with certainty.
Final Answer:
\[
\boxed{\text{(B)}}
\]

- Diversity may bring people to the same room, but inclusion ensures that every voice is heard, valued, and allowed to shape the conversation. It demands that institutions go beyond representation to transformation, to question who holds the power, who defines norms, and whose stories remain unheard. It is the process of turning the promise of democracy into practice, one case, one reform, and one act of courage at a time.

Fact: Seema owns a perfume factory that lawfully stores large quantities of chemicals used in fragrance production. One night, a sudden lightning strike causes a fire, leading to the release of toxic fumes that harm nearby residents. Seema had complied with all safety requirements and had fireproof storage facilities in place.

The induced emf in a 3.3 kV, 4-pole, 3-phase star-connected synchronous motor is considered to be equal and in phase with the terminal voltage under no-load condition. On application of a mechanical load, the induced emf phasor is deflected by an angle of \( 2^\circ \) mechanical with respect to the terminal voltage phasor. If the synchronous reactance is \( 2 \, \Omega \), and stator resistance is negligible, then the motor armature current magnitude, in amperes, during loaded condition is closest to: \[ {(round off to two decimal places).} \]
