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.

Explanatory Answer

Method of solving this CAT DILR Question from Data Tabulation question

Correct Option: D

Solution:

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
Geeta should have scored a CS of more than 52 so she should have scored 19 or 20 in WE. But Ajay was the unique highest scorer in WE.
So, Geeta should have score 19 in WE.
Options 1 and 2 are both true. Option 3 is not true.
Therefore Both 1 and 2
