In the following question, one statement is given, followed by two conclusions I and II. You have to consider the statements to be true, even if they seem to be at variance from commonly known facts. You have to decide which of the given conclusions, if any follow from the given statement. Statement: People generally prefer driving their own vehicles over public transportation to go for work which leads to increase in pollution. People should use public transportation or atleast use carpooling if they care to bring down pollution levels. Conclusion I: Using Public transportation or carpooling will bring down the rising pollution levels. Conclusion II: People who use personal vehicles instead of public transportation are rich.

A

If only conclusion I follows

B

If only conclusion II follows

C

If either I or II follows

D

If neither I nor II follows

For the standard transportation linear programme with m sources and n destinations and total supply equaling total demand, an optimal solution (lowest cost) with the smallest number of non-zero xij values (amounts from source i to destination j) is desired. The best upper bound for this number is

A

mn

B

2 (m + n)

C

m + n

D

m + n - 1

When demand for a factory's products is high, more money is spent at the factory for safety precautions and machinery maintenance than demand is low. Thus the average number of on-the-job accidents per employee each month should be bower during periods when demand is high than when demand is low and less money is available for safety precautions and machinery maintenance. Which of the following,if true about a factory when demand for its product is high casts the most serious doubt on the conclusion drawn above?

A

Its employees ask for higher wages than they do at other times.

B

Its management hires new workers but lacks the time to train them properly.

C

Its employees are less likely to lose their jobs than they are at other times.

D

Its management sponsors a monthly safety award for each division in the factory.

when demand for factory's products is high . more money is spent at the factory for safety precautions and machinery maintenance than when demand is low. thus the average number of on -the-job accidents per employee each month should be lower during perids when demand is high than when demand is low and less money is available for safety precautions and machinery maintenance .when demand for its products is high, casts the most serious doubt on the conclusion drawn above?

A

Employees demand for higher wages than they do at other times.

B

Authority hires new workers but lacks the time to rain them properly.

C

Employees are less likely to lose their jobs than are at other times.

D

Authority sponsors a monthly safety award for each division in the factory.
