CAT DILR : CAT 2018 Question Paper Slot 1

Set 1 : Written Test

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:

Explanatory Answer

Method of solving this CAT Question on CAT DILR
CAT DI LR 2018 Slot 1

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.
CAT DI LR 2018 Slot 1
Ajay was the unique highest scorer in WE.
CAT DI LR 2018 Slot 1
CAT DI LR 2018 Slot 1
Danish, Harini, and Indu had scored the same marks the in GA.
Indu and Jatin both scored 100% in exactly one section and Jatin’s composite score was 10 more than Indu’s.
Indu and Jatin both scored 100% in exactly one section and Jatin’s composite score was 10 more than Indu’s.
Now, if Indu had scored 100% in DI, then her CS would be 20 × 2 + 8 + x = 60 or, x should be 12.
Now, this is a problem as Indu could have less than 70% in 2 sections and so would not have been selected.
So, x = 20. CAT DI LR 2018 Slot 1
Indu and Jatin are in. The highest CS Geeta can get is 54, so Ester is also in.
Ajay could not have scored 19 in WE as his CS would then become 51 same as Danish.
So, Ajay should have scored 20 in WE resulting in an CS of 52.
CAT DI LR 2018 Slot 1
CAT DI LR 2018 Slot 1
Harini could not have scored 20, 19 or 18. If Harini had sored 17, her CS would have been 47 same as Falak. So, 17 is also ruled out.
16 and 15 are also ruled out. Hmax could be 14. This gives us a CS of 44 which should be fine.
WE of 14 works.

The question is "If all the candidates scored different marks in WE then what is the maximum marks that Harini could have scored in WE? [TITA]"

Hence, the answer is 14 marks
