Solutions:

LRDI 1 Sprint Solutions

Set 1

1. Let the total number of factories be 1000. So, there are 903 factories that are wholly private. The total number of employees is 60*1000 = 60000 out of which, wholly private has 64.6% i.e. 38760. So, average employment will be approximately 43.

2. This is extremely straightforward and you have to simply take the ratio of value added to the employment. So, 1.8 is the highest value that we get from Central and States or Local Governments.

3. Again it is calculation based and so, we need to get the ratio of Gross output to the Fixed capital. Option b is correct.

4. Simple calculation based question again and so, we need to figure out the ratios value added:employment and value added:fixed capital. Option c is correct.

5. 1.8% of total firms is 2700. Total firms are 150000.

Central government has 1500 factories. Value added by Central Government = 14.1% of 1,40,000 crore = 19,740.

Hence, required average value added = 19740/1500 = Rs. 13.1 crore.

6. You need not even calculate here. The fall for India is by 1 point whereas that for the others is by 1 point or 0.5 points. So, it is fairly obvious that India would show the highest change (remember, we are not supposed to check the fall or rise but the absolute change) as it has the lowest denominator.

7. The chart talks about only growth rates and so, we cannot comment on the absolute values.

8. We would need to assume that the GDP of India in 1997 to be x.

For 1998, India’s FEI = 0.72 * 102x/100 = 0.7344x

And foreign equity inflows for 1997 = 1.71x

For China, let’s assume the GDP to be y. Then, FEI in 1998 = 107y/100 × 4.8 = 5.136y. And FEI in 1997 = 5.96y.

For South Korea, let GDP be z.

FEI in 1998 = 95z/100 × 2.5 = 2.375z and FEI in 1997 = 2.16z.

FEI of India and China were lower in 1998 than in 1997, while that of South Korea was higher in 1998 than in 1997. Option d.

9. Let China’s GDP in 1998 be x and that of India be y

4.8/x = 7.2/y

x/y = 2/3

Option c is correct.

10-14. The key to solving this lies in the representation. The table below might just be the best way to show the data and simplify it further.

The key thing to notice here is that, in all races we know who the winners will be and so, the only way E can score 5 points is through a 3-1-1 split. Post that, everything else is derivable.

10. b

11. d

12. a

13. c

14. For the 14th question, the table would change by a bit.

The first one is invalid and so, we get d as the correct answer.

15-19

The easiest way to do this is to understand from where the students are entering a class and how they are leaving and then balance the two.

In short, we can rely on this nice little chart:

Now, we know that the horizontal arrow represents the students who have failed and the slant arrow represents the students who have passed. So, the figure under 2016 is a sum of the two arrows that reach that particular block and the figure under 2015 is split into two parts. Now it becomes easy to visualize the questions.

15.

Pass percentage is 30/36. Option c

16.

Option d.

17.

Option e.

18.

Count all the horizontal lines which will give us 182. Option b.

19.

The important thing to note here will be the limiting factor. You cannot start with class 1 itself as you are bound to get stuck somewhere in between. So, what you can do is, look at the previous figure and understand where the lowest failures will lie. So, class 5 is your limiting condition and so, we will start backtracking from class 5. Option a is correct.
