GATE 2024 PI – Question 61

Industrial Engineering · Work System Design · 2 marks · Numerical answer

A packaging worker rated 120% takes an observed average nine minutes. Allowances are 10% of standard time. Find standard time (integer minutes).

Show answer and explanation

Correct answer: 12 to 12

Explanation

Normal time is $9(1.20)=10.8$ minutes. If standard time is S, normal work occupies 0.9S, so $S=10.8/0.9=\mathbf{12}$ minutes.
