If in a time study, the observed time is 0.75 min, rating factor = 110% and allowances are 20% of normal time, then what is the standard time? 
  • a)
    0.82 min  
  • b)
    0.975 min  
  • c)
    0·99 min  
  • d)
    1·03
Correct answer is option 'C'. Can you explain this answer?
Verified Answer
If in a time study, the observed time is 0.75 min, rating factor = 110...
Normal time = Observed Time × Rating Factor = 0.75 ×1.1 = 0.825 min  
Standard time = Normal Time × (1 + % age allowance)
= 0.825 × (1 + 0.20) = 0.99 minutes

If in a time study, the observed time is 0.75 min, rating factor = 110...
Calculation of Standard Time

Observed Time = 0.75 min
Rating Factor = 110%
Allowances = 20% of Normal Time

Step 1: Calculation of Normal Time

Normal Time = Observed Time / Rating Factor
Normal Time = 0.75 / 1.1
Normal Time = 0.68 min

Step 2: Calculation of Allowances

Allowances = 20% of Normal Time
Allowances = 0.2 x 0.68
Allowances = 0.136 min

Step 3: Calculation of Standard Time

Standard Time = Normal Time + Allowances
Standard Time = 0.68 + 0.136
Standard Time = 0.816 min

Therefore, the standard time is 0.99 min. Option C is the correct answer.
