Question

a worker is allowed 70 hours for a job actual time taken is 50 hours rate per hour is Rs 10. wage as per Halsey plan is​

Answer 1

Answer:

Given in the problem is Standard hours 60

Basic wages is 10 per hour

Wages under Rowan scheme is 12 per hour. So difference 2 per hour is the incentive under Rowan.

Now Rowan incentive formula is (Actual hours / Std hours) (Time saved) (Basic Rate)

Let time saved be assumed to be x

Substituting in formula (x/60)(60-x)*10 = 2x

(x/60)(60-x) = 0.2x

x(60-x) = 12x

60x - x-squared = 12x

-x squared = -48x

x squared = 48x

x = 48 so Actual hours worked is 48

Answer 2

TOTAL WAGES EARNED DURING UNDER ROWAN PLAN 60x12= 720
TOTAL BONUS EARNED DURING UNDER ROWAN PLAN 720-60X10=120
ACTUAL TIME SAVED FOR WORK= 120/10=12 HOURS
ACTUAL TIME TAKEN=60-12=48 HOURS
WAGES UNDER HALSEY PLAN (48X10+120*50/100)= 540/- ANS (B)
