3. 

In which of the given years the number of candidates appeared from State P has maximum percentage of qualified candidates?

[A]. 1997
[B]. 1998
[C]. 1999
[D]. 2001

Answer: Option D

Explanation:

The percentages of candidates qualified to candidates appeared from State P during different years are:

For 1997 ( 780 x 100 ) % = 12.19%.
6400

For 1998 ( 1020 x 100 ) % = 11.59%.
8800

For 1999 ( 890 x 100 ) % = 11.41%.
7800

For 2000 ( 1010 x 100 ) % = 11.54%.
8750

For 2001 ( 1250 x 100 ) % = 12.82%.
9750

Therefore Maximum percentage is for the year 2001.

Is there an easier to find out the solution without doing the entire calculation??

Aman said: (Jul 13, 2011)  
Yup just compare all the Qualified figures with each other you'll get maximum qualified candidates in 2001.

Praveen said: (Jun 21, 2012)  
Find the maximum percentage right.

Take the difference between appeared and qualified.

1997------>5620.

1998------>7780.

1999------>6910.

2000------>7740.

2001------>8500.

So difference high in 2001. So that is answer.

Thanks praveen. The way you explained is the most simplest.

Ritesh said: (Aug 27, 2012)  
@Praveen is it applicable on all similar questions.

Joh said: (Apr 15, 2013)  
Dear @Praveen as per your idea its good, but after 2001 immediate high difference will be as per your idea 7780(in 1998) , but as per solving entire problem it is coming 1997, how come it can apply for all the problems? please justify.

Rakesh said: (Apr 4, 2014)  
I think taking difference will not work all the time.

Reason: consider case 1: applied 5 and qualified 1. difference is (5-1) = 4.

Case 2: applied 10 and qualified 7 difference is (10-7) = 3.

Now, as per above logic since case 1 difference value is more we expect case 1 percentage as higher but in reality case 1 percent is 1/5 = 2/10 = 200/10% = 20%.

And case 2 is 7/10 = 700/10% = 70%.

Clearly, case 2 is higher :-(.

Well we can use the formula:.

Final value-original value/original value.

Final value will be current year.

Original value will be previous year.

Tara said: (Jun 10, 2016)  
Just see the highest figure of qualified candidates from state P in all the years.

Jithin said: (Jun 24, 2016)  
@Tara.

It is not correct. If the denominator is also high percentage will be less.

Shivangi Gupta said: (Aug 6, 2016)  
I read all the above comments, so basically there is no other way to find out the highest percentage other than to just calculate. As observations turn out to be right only in sometimes.

S J Prakash said: (Oct 6, 2016)  
How to calculate the percentage? Please guide me.

Suresh Kumar said: (Oct 29, 2016)  
@Merina.

Which is having the highest denominator, that percentage take a maximum. i.e 9750 is highest dmnatr so it maximum.

Rudraksh Barnwal said: (Jun 25, 2017)  
We can solve this question by -appear/qualify*100.

Karthi said: (Sep 8, 2018)  
@Praveen.

Your answer is correct.

One thing to note is that we are getting total failed by subtracting. So the least failed is high pass percentage.

Nai said: (Sep 2, 2019)  
I think it should be appear/qualified but why they put qualified/appear? Could anyone explain me this?

Ankita Thakur said: (Jul 16, 2020)  
I think we can do round off of all the figures.

In multiples of 100; Like;

780/6400*100 = 80000/6400 = 12%apporx.
1020/8800*100 =100000/9000,
890/7800*100 = 90000/8000,
1010/8750*100 =100000/9000,
1250/9750*100 =130000/10000 = 13%approx.
Answer Will be 2001(D).

Gopal said: (Jul 19, 2021)  
The answer would be in approximation terms(to the nearest round off number, 100 multiple)
Then compare the fraction value;

1997------>6400(800) --> 1/8,
1998------>8800(1000) --> 1/8.8(approx 1/9),
1999------>7800(900)--> 1/8.7,
2000------>8800(1000)--> 1/8.8(approx 1/9),
2001------>9800(1300)-->1/7.5.

So, less denominator value in 2001. So this is the possible answer.

Very good, Thanks @Gopal.
