We will be solving interesting sets as a part of this series LRDI of the Day. I will be posting a video solution by the end of the day. You can keep a track of all the sets by clicking here: LRDI of the Day

#LRDIoftheDay #3

A scorcher of a set. If you can solve this within 10 minutes, you are all set to crack LRDI 2017.

Kaushal, Pushkar and Vyoma are students who appeared for the IIFT entrance test in November 2017 (yeah, time-turner it is!). Each of the three mentioned students solved all the six different sections namely QA, DI, LR, VA, RC and GK. The following table provides information about the marks obtained by each student in every section as a percentage of the aggregatenumber of marks obtained by that student in all the six sections.

The marks lost by each of the three students in each of the six sections are due to five different reasons namely: Did not know the concept, Did not see the question, Made a silly mistake, Havenâ€™t completed the syllabus and Lack of confidence. The following table provides information about the marks lost by each student due to each of the mentioned reasons as a percentage of the aggregate marks lost by that student in QA. This holds true for all the given six sections.

The marks lost by Kaushal, Pushkar and Vyoma in each section as a percentage of the marks obtained by each one of them in that section is 40%, 25% and 20% respectively.

1. If the total marks obtained by Vyoma, Pushkar and Kaushal in all the sections are in the ratio 1: 2: 5, then the marks obtained by Pushkar in DI as a percentage of aggregate marks obtained by Vyoma in DI and Kaushal in GK is

(1) 20% (2) 16% (3) 15% (4) 18%

2. If the marks lost by Kaushal, Vyoma and Pushkar in VA is the same, then the marks lost by Pushkar in LR because of silly mistakes as the percentage of the total marks obtained by Kaushal in all the sections is

(1) 2% (2) 0.6% (3) 1% (4) 1.5%

Additional Information for questions 3 and 4:

The marks obtained by Kaushal in QA are not fewer than the marks obtained by Pushkar in DI and marks obtained by Pushkar in VA are not fewer than the marks obtained by Vyoma in RC.

3. If the marks obtained by Vyoma in GK is 144, then at least how many marks are obtained by Kaushal in LR?

(1) 25.25
(2) 40.25
(3) 48.75
(4) 37.5

4. If the marks lost by Pushkar in VA because he did not see the question is 45, then the marks lost by Vyoma in QA due to reason lack of confidence cannot be more than

(1) 50 (2) 32 (3) 36 (4) 40
