A company administers a written test comprising of three sections of 20 marks each - Data Interpretation (DI), Written English (WE) and General Awareness (GA), for recruitment. A composite score for a candidate (out of 80) is calculated by doubling her marks in DI and adding it to the sum of her marks in the other two sections. Candidates who score less than 70% marks in two or more sections are disqualified. From among the rest, the four with the highest composite scores are recruited. If four or less candidates qualify, all who qualify are recruited.
Ten candidates appeared for the written test. Their marks in the test are given in the table below. Some marks in the table are missing, but the following facts are known:
Q.1: Which of the following statements MUST be true?
Q.2: Which of the following statements MUST be FALSE?
Q.3: If all the candidates except Ajay and Danish had different marks in DI, and Bala's composite score was less than Chetna's composite score, then what is the maximum marks that Bala could have scored in DI?
Q.4: If all the candidates scored different marks in WE then what is the maximum marks that Harini could have scored in WE?
Jatin scored 100% in exactly one section. So, Jatin's scored 20 in DI.
Jatin's composite score = (20 × 2) + 16 + 14 = 70
Given, Indu was recruited and Indu scored 100% in exactly one section.
Indu's score is 70 – 10 = 60
If Indu scores 20 in DI, Indus's score in GA = 60 – 40 – 8 = 12
In this case, Indu will not quality Hence, Indu scored 20 in GA.
⇒ score in DI = 60 − 20 − 82 = 32/2 = 16
⇒ Danish, Harini and Indu scored 20 in GA.
Score of Danish = 2(8) + 15 + 20 = 51
Hence, Score of Ajay = 2(8) + 20 + 16 = 52
As Ajay scores either 19 or 20 in DI, the composite score cannot be 51.
