Elements Observed time (min) Rating Basic Time (Normal Time)
I 1 100 % = 1 X (100/100) = 1
II 2 110 % = 2 X (110/100) = 2.2
III 3 120 % = 3 X (120/100) = 3.6

Total Normal Time = 1 + 2.2 +3.6 = 6.8 min

Allowances : % Allowance X Normal Time

For I, = (20/100) X 1 = 0.2 min

For II, = (15/100) X 2.2 = 0.33 min

For III, = (10/100) X 3.6 = 0.36 min

Standard Time = Normal Time + Allowances

Standard Time for I = 1 + 0.2 = 1.2 Min

Standard Time for II = 2.2 + 0.33 = 5.53 Min

Standard Time for III = 3.6 + 0.36 = 3.96 Min
