(a) fixed cost and variable cost are equal
(b) sales revenue and total cost are equal
(c) sales revenue is more than total cost
(d) sales revenue is less than total cost.

Ans: (b) sales revenue and total cost are equal

##### Q12. Standard time is equal to

(a) normal time + idle time
(b) normal time + allowances
(c) normal time + idle time + allowance
(d) normal time – allowance

Ans:  (b) normal time + allowances

##### Q13. The maximum level of inventory of an item is 100 and it is achieved with infinite replenishment rate. The inventory becomes zero over one and half month due to consumption at a uniform rate. This cycle continues throughout the year. Ordering cost is  100 per order and inventory carrying cost is  10 per item per month. Annual cost (in `) of the plan, neglecting material cost, is

(a) 800
(b) 2800
(c) 4800
(d) 6800.                                                                                   (GATE-ME-2007)

Ans:  (d) 6800.

##### Q14. In a single serve infinite population queuing model, arrivals follow a Poisson distribution with mean λ = 4 per hour. The service times are exponential with mean service time equal to 12 minutes. The expected length of the queue will be

(a) 4
(b) 3.2
(c) 1.25
(d) 24.3                                                                                            (GATE-ME-2000)

Ans:  (b) 3.2

##### Q15. The supply at three sources is 50, 40 and 60 units respectively while the demand at the four destinations is 20, 30, 10 and 50 units.

In solving this transportation problem
(a) a dummy source of capacity 40 units is needed
(b) a dummy destination of capacity 40 units is needed
(c) no solution exists as the problem is infeasible
(d) none solution exists as the problem is degenerate.                      (GATE-ME-2002)

Ans:  (b) a dummy destination of capacity 40 units is needed

##### Q16. The mathematical technique, employed to pick the best choice from among several alternatives, is known as

(a) production planning
(b) production control
(c) linear programming
(d) value analysis.

Ans:  (c) linear programming

##### Q17. CPM stands for

(a) common project method
(b) common path method
(c) critical project method
(d) critical path method

Ans:  (d) critical path method

##### Q18. In PERT analysis a critical activity has

(a) maximum float
(b) zero float
(c) maximum cost
(d) minimum cost                                                                                  (GATE-ME-2004)

Ans:  (b) zero float

##### Q19. Consider a single server queuing model with Poisson arrivals (λ = 4/hour) and exponential service (μ = 4/hour). The number in the system is restricted to a maximum of 10. The probability that a person who comes in leaves without joining the queue is

(a) 1/11
(b) 1/10
(c) 1/9
(d) 1/2.                                                                                                    (GATE-ME-2005)

Ans: (a) 1/11

(c) decreases continuously
(d) none of the above.

Ans:  (a) remains constant
