  2. i and iii
  3. iii and iv
  4. ii and iii
Correct answer: (D)
ii and iii

226. A decision table is

  1. a truth table
  2. a table which facilitates taking decisions
  3. a table listing conditions and actions to be taken based on the testing of conditions
  4. a table in a Decision Support System
Correct answer: (C)
a table listing conditions and actions to be taken based on the testing of conditions

227. In the following word statement the actions are "if a student gets 50 marks or more in mathematics and 40 marks or more in English he passes the examination, otherwise he fails"

  1. student passes the examination
  2. student fails the examination
  3. student gets 50 marks or more in mathematics
  4. student mathematics marks >= 50 and student English marks >= 40
  1. i and ii
  2. i and iii
  3. ii and iii
  4. iii and iv
Correct answer: (A)
i and ii

228. In a limited entry decision table a-entry against a condition signifies that

  1. the outcome of testing the condition is irrelevant
  2. it is an important condition
  3. the condition should be tested
  4. the condition is a Boolean condition
Correct answer: (A)
the outcome of testing the condition is irrelevant

229. In a limited entry decision table the action entries

  1. list X or - corresponding to actions to be executed
  2. list the conditions to be tested
  3. have Y or N or - entries
  4. list the actions to be taken
Correct answer: (A)
list X or - corresponding to actions to be executed

230. The following structured Englishprocedure is incorrect because
if balance in account <=0
then
{issue exception note to dept.
mark "stop future issues" in
departments record}
else
if balance in account <minimum balance
then
{ issue item to dept.
issue warning to dept.}
end if
end if

  1. end if in second if is not needed
  2. nesting of ifs is not correct
  3. no action is specified when balance in account >=minimum balance
  4. the value of minimum balance is not specified
Correct answer: (C)
no action is specified when balance in account >=minimum balance
