A time study of a restaurant activity yielded a cycle
time of 2'00 minutes, and the waitress was rated
at PR : 96 per cent. The restaurant chain has a
2O per cent allowance factor. Find the standard time.

Sol : Average time = 2 mins

Normal time = Average time X Performance rating(PR)
= 2 X .96
= 1.92
Standard time = Normal time X Allowances
= 1.92 + 1.92(0.20)
= 2.304 mins
