Question 1 of 5
1. Question
The Plastic Waste Management Rules, 2016 are clear that producers, importers and brand owners must adopt a collect-back system for the plastic they introduce into the environment. Although the rules were notified in the same year, amended later and given high visibility by the Ministry of Environment, Forest and Climate Change, not much has been done to take the process forward. At the very least, local bodies should consult manufacturers or importers to assess the problem. Delaying such a measure has created the anomalous situation of small producers of plastics facing the ban, while more organised entities covered by the Extended Producer Responsibility clause continue with business as usual. Such enforcement failure is not an argument in favour of relaxing the prohibition on flimsy plastics that are typically used for under 15 minutes, but to recover thousands of tonnes of waste that end up in dumping sites. Cities and towns need competent municipal systems to achieve this.
Which of the following is the most logical and critical inference that can be drawn from the above passage?
Correct
Ans. B. The focus of the passage is on explaining how the plastic waste management rules have not proven effective and what more can be done by municipal committees in this regard. Hence B is the most accurate and critical inference.

Question 2 of 5
2. Question
Ms. Cigy was to earn Rs.300 and a memento for seven weeks’ work. However, she worked for only 4 weeks and ended up earning Rs.30 and a memento. What is the value of the memento?
Correct
Solution: B
Let the value of the memento be Rs. x.
Then, pay for seven weeks’ work = Rs. 300 + x.
Pay for one week’s work = Rs. (300+x)/7So, pay for four week’s work = Rs. [(300+x)/7] *4 ..(i)
Now, this is equivalent to Rs. 30 + x. ..(ii)
Equating (i) and (ii)
Þ [(300+x)/7] *4 = (30+x)Þ 4x + 1200 = 7x + 210
Þ 3x = 990
Þ x = Rs. 330
Hence , option (b) is correct .Incorrect
Solution: B
Let the value of the memento be Rs. x.
Then, pay for seven weeks’ work = Rs. 300 + x.
Pay for one week’s work = Rs. (300+x)/7So, pay for four week’s work = Rs. [(300+x)/7] *4 ..(i)
Now, this is equivalent to Rs. 30 + x. ..(ii)
Equating (i) and (ii)
Þ [(300+x)/7] *4 = (30+x)Þ 4x + 1200 = 7x + 210
Þ 3x = 990
Þ x = Rs. 330
Hence , option (b) is correct . -

3. Question
If 6th day of August is Saturday, then what will be the day on 4th day from 21 st of the next month?
Correct
Solution: C
August has 31 days.
4th day from 21st of next month means 25th September.
Number of days from 6th August to 25th September = (31-6) + 25 = 50 days
Number of odd days= 1 day (7 weeks + 1 day)
Means it will be Sunday on 25th September.Hence, option(c) is correct.

Question 4 of 5
4. Question
A typewriter types 500 letters in a min. After typing every page, he takes 30 seconds to change the page. If one page contains 300 letters, then how many pages does he type in 11 min?
Correct
Solution: B
The typewriter can type 500 letters in 60 seconds.
∴ Speed of typing = 500/60 = 25/3 letters per sec
He takes 30 seconds to change the page.
∴Total time in typing one page plus changing the page = 300/(25/3) + 30 = 36 + 30 = 66 sec
∴In 11 min, i.e. 660 seconds, the number of pages he can type = 660/66 = 10 pages
It is important to note that after typing the 10thpage, when Amit changes the page, 11 min gets over (i.e. just before he starts typing the 11th page).Hence, option(b) is correct.

Question 5 of 5
5. Question
In a row of 16 boys, when Parvez was shifted by two places towards left, he became 7th from the left end. What was his earlier position from the right end of the row?
Correct
Solution: B
Total number of boys in a row = 16.
As we know, when Parvez was shifted by two places towards left, he became 7th from the left end.
So, his original position from the left end = 9th
Position from the right end = 16 – 9 + 1= 8th
Hence, option (b) is the correct.Incorrect
