Answer the next 3 questions based on the information given below:
In a class of 8 students students were ranked according to their marks in 'Quant' section as given in the table.
Now, each student recieved zero or more than zero marks in the LRDI section.
Following observations were made based :
- Total marks scored in LRDI section by all students did not exceed 60.
- The rank of any student after adding marks for LRDI section was not the same as that before.
- The marks of no two students were same.
If exactly 2 students scored non-zero marks in LRDI section, what is the minimum total marks scored by all of them in LRDI section?
Solution

Answer the next 4 questions based on the information given below.
Company XYZ has two types of products – A & B. Every year, the company sells all the products that it manufactures in that particular year. The production of ‘A’ commenced in 2016. Exactly 10% of the quantity of ‘A’ sold in a year is discarded exactly two years later; another 10% (of the total) is discarded in the next year and so on, so that the entire quantity of A manufactured in a year is completely discarded exactly at the end of eleven years. It is also known that the company manufactured at least 100 units of ‘A’ each year and did not manufacture the same quantity in any two years.
The production of ‘B’ started in 2018. 20% of the units of ‘B’ that are sold in a year are discarded exactly two years later; another 20% (of the total) is discarded in the next year and so on, so that the entire quantity of B manufactured in a year is completely discarded exactly at the end of six years. The bar graph below gives the number of units of these products that were in use by the citizens in the given years.
How many units of A were manufactured in 2016?
- (a)
100
- (b)
150
- (c)
None of these
- (d)
Cannot be determined
How many units of A were discarded in 2020?
How many units of A were manufactured by the end of 2021?
- (a)
790
- (b)
810
- (c)
800
- (d)
None of these
How many units of B were discarded by the end of 2021?
Answer the next 4 questions based on the information given below.
The government is planning to reintroduce Cheetahs in the country which earlier went extinct. It plans to introduce 160 Cheetahs equally across 8 national parks. The induction is planned to be completed in 4 phases. Table below shows the number of Cheetahs inducted in each of the 8 parks in phase 1 and 2.
Number of Cheetah’s inducted in any phase in any park is between 1 and 9 (including both). It is known that, in a particular phase, no two parks get an equal number of Cheetahs. The number of Cheetahs inducted in park A in phase 4 is more than that in phase 3.
How many Cheetahs were inducted in park F in phase 3?
Total how many Cheetah’s were inducted in phase 4?
- (a)
35
- (b)
36
- (c)
37
- (d)
Cannot be determined
Which park got the least number of Cheetah’s in phase 4?
- (a)
A
- (b)
C
- (c)
