10. 14 Marks
    A work sampling study showed that $30\%$ of a work of $50$ hours was consumed by avoidable delays. If each time a work sampling observation was made the operator was rated and the average of such rating was $110\%$. If $100$ units were produced by the operator in that period. Calculate standard time.
    How to answer

    • Calculate effective working time excluding avoidable delays
    • Apply rating 110% to get normal time
    • Divide by 100 units to get normal time per unit
