Sr. No.	Element	Observed time in minutes	Rating	Basic time (Normal time)
1	a	1	125%	1 x (125/100) = 1.25 min
2	b	1.5	120%	1.5 x (120/100) = 1.8 min
3	c	2	110%	2 x (110/100) = 2.2 min

Total Normal time = 1.25 + 1.8 + 2.2 = 5.25 min

Allowances = % Allowance X Normal Time

For

a = (20/100 x 1.25) = 0.25 min

b = (15/100 x 1.8) = 0.27 min

c = (20/100 x 2.2) = 0.44 min

Standard time= Normal time + Allowances

For

a = 1.25 + 0.25 = 1.5 min

b = 1.8 + 0.27 = 2.07 min

c = 2.2 + 0.44 = 2.64 min
