(b) mean absolute deviation percentage error
(c) mean standard deviation error
(d) mean square error

Solutions
S1. Ans. (c)
Sol. Breakeven point (BEP) indicates that it recovers fixed cost and variable cost.
S2. Ans. (d)
Sol. When we increase economic order quantity, then the total cost first decreases and then increases. As shown in the graph.

Order Size
S3. Ans. (d)
Sol. In inventory control, the factors on which EOQ depends on
Holding cost
Ordering cost
Consumption rate
EOQ=(2DC_o)/C_h
S4. Ans. (a)
Sol. As we know that
EOQ=(2DC_o)/C_h
Where,
D=Annual Demand=400
C_o=Ordering cost=Rs.144 per order
C_h=Holding cost=Rs.8 per unit per year
EOQ=(2×400×144)/8=120
S5. Ans. (a)
Sol. Delphi technique: The Delphi technique is used in forecasting and it is used as group opinions of the panel of experts on the problem being encountered.
S6. Ans. (d)
Sol. The most commonly used method for measuring forecast error is mean square error.
MSE=(∑▒〖(D_t 〗-F_t)²)/N
