Excess fat breakdown → ketone body production
Accumulation of ketoacids → metabolic acidosis
Compensatory hyperventilation (Kussmaul breathing) → \\text{PaCO}_2 falls (respiratory compensation)

Expected ABG in DKA:

Parameter	Value	Interpretation
pH	< 7.35	Acidosis
\\text{PaCO}_2	< 35 mmHg	Respiratory compensation (hyperventilation)
\\text{HCO}_3^-	< 18 mEq/L	Primary metabolic loss

Option B (pH 7.28, PaCO₂ 28, HCO₃ 10) fits perfectly — metabolic acidosis with respiratory compensation.

Physics QUESTION #7327

Question 1064

A body is projected at such an angle that the horizontal range is three times the maximum height. The angle of projection is:

$25°$
$33°$
$42°$
$53°$✔️

Correct Answer Logic:

Range: $R = \dfrac{u^2\sin2\theta}{g}$, Max height: $H = \dfrac{u^2\sin^2\theta}{2g}$

Given $R = 3H$: $\dfrac{\sin2\theta}{1} = 3\cdot\dfrac{\sin^2\theta}{2} \Rightarrow 2\sin\theta\cos\theta = \dfrac{3}{2}\sin^2\theta$

$\Rightarrow \tan\theta = \dfrac{4}{3} \Rightarrow \theta = \tan^{-1}\!\left(\dfrac{4}{3}\right) \approx \mathbf{53°}$

J Limited makes furniture with a mark-up of 40%. A job 10 km away involves: Materials $400; Labour $240; Travel $2 per km each part of journey. What price will the company quote?

$916
$924
$936

Correct Answer Logic:

Option D ($952) is correct.

Civil Procedure QUESTION #5668

Question 1068

After a jury trial, a party moves for Judgment as a Matter of Law (JMOL) under Rule 50(b) within 28 days of the entry of judgment. The party did not make a Rule 50(a) motion before the case was submitted to the jury. How should the court rule?

Grant the motion if the evidence is insufficient as a matter of law.
Deny the motion because a Rule 50(a) motion is a prerequisite for a Rule 50(b) motion.✔️
Grant the motion but only if the party shows 'manifest injustice'.
The court can only grant a new trial, not JMOL, if no Rule 50(a) motion was made.

Correct Answer Logic:

Rule 50(b) allows a party to file a 'renewed' motion for JMOL. You cannot 'renew' a motion that was never made. Therefore, a Rule 50(a) motion during trial is a necessary prerequisite.

Question 1069

A Ministry wishes to write off an irrecoverable loss of Rs. 8 million due to a theft that discloses a defect in the system requiring orders from higher authority. Under Annex-I what is the CORRECT procedure?

Since this loss discloses a systemic defect condition (a) is not met and the write-off cannot be processed under these delegated powers regardless of the amount.

Accounting & Finance QUESTION #6120

Question 1074

An employee works 40 hours/week at $8/hour. Bonus: 30% of hourly rate per hour of time saved. Standard time: 30 minutes per unit. Last week: 40 hours worked, 90 units produced. What were her total earnings?

$320
$332✔️
$360
$416

Correct Answer Logic:

Option B ($332) is correct.

Basic pay: 40 × $8 = $320

Allowed time for 90 units = 45 hours; Actual = 40 hours; Time saved = 5 hours

Bonus = 5 × (30% × $8) = 5 × $2.40 = $12

Total = $320 + $12 = $332
