Q.A job has a Time Allowed of 10 hours at a Time Rate of ₹20 per hour. The worker completes it in 8 hours. Calculate the Bonus and Total Earnings under BOTH the Halsey and the Rowan Premium Bonus Schemes, and state which scheme gives the worker the higher total earnings on this job.

With time saved (2 hours) well below 50% of the time allowed, Rowan's larger fractional weighting on the time actually worked gives the worker a bigger bonus here than Halsey's flat 50% share does.

Time Saved = 10 − 8 = 2 hours (20% of Time Allowed — below the 50% crossover point). …

Time Saved = 10 − 8 = 2 hours, which is 20% of the Time Allowed — well below the 50% crossover point (Section 4.C), so Rowan is expected to pay the larger bonus here.

Halsey Scheme:

Bonus = 50% × 2 × ₹20 = ₹20.

Basic Wages = 8 × ₹20 = ₹160.

Total Earnings = 160 + 20 = ₹180.

Rowan Scheme:

Time-Saved Ratio = 2 ÷ 10 = 0.20.

Bonus = 0.20 × 8 × ₹20 = ₹32.

Basic Wages = 8 × ₹20 = ₹160 (identical to Halsey — Basic Wages never depend on which scheme is used).

Total Earnings = 160 + 32 = ₹192. …

Students sometimes assume Halsey always pays less than Rowan (or vice versa) as a fixed rule — which scheme pays more genuinely depends on what fraction of Time Allowed was saved; Questi …
