Number of students (in lakhs)


Percentage distribution of streams

1
By what percent is the number of students who graduated in finance stream in 2013 is more than or less than the number of students who graduated in commerce stream in 2015?
» Explain it
A
Number of students who graduated in finance stream in 2013 = 9.9% of 22 lakhs = 2.178 lakhs

the number of students who graduated in commerce stream in 2015 = 7.4% of 25 lakhs = 1.85 lakhs

Reqd. % =  2.178 – 1.85  × 100 =  32.8  % = 17.73% more
1.85 1.85

Hence, option A is correct.

2
Find the difference between the sum of the number of students who graduated in commerce during the year 2012, 2013, and 2014 and the sum of the number of students who graduated in finance stream during the year 2015, 2016, and 2017.
» Explain it
C
The sum of the number of students who graduated in commerce during the year 2012, 2013, and 2014 = 7.4% of 16 lakhs + 7.4% of 22 lakhs + 7.4% of 24 lakhs = 7.4% of 62 lakhs = 4.588 lakhs 
 
the sum of the number of students who graduated in finance stream during the year 2015, 2016, and 2017 = 9.9% of 25 lakhs + 9.9% of 32 lakhs + 9.9% of 28 lakhs = 9.9% of 85 lakhs = 8.415 lakhs 
 
Difference = 8.415 – 4.588 = 3.827 lakhs 

Hence, option C is correct.
 
3
In 2013 the ratio of First Class Division holder(FCD) in different streams was A : C : E : F : H : P : M = 2 : 1 : 1 : 3 : 4 : 2 : 1 and the total number of students who scored FCD was 2.8 lakhs then how many percent of the engineering students had scored FCD?
» Explain it
A
A : C : E : F : H : P : M = 2 : 1 : 1 : 3 : 4 : 2 : 1, assume it A = 2X, C = X, E = X, F = 3X, H = 4X, P = 2X, M = X

According to question, the sum of the FCD holder 2x + x + x + 3x + 4x + 2x + x = 14x = 2.8 lakhs

So, the value of x = 0.2

Number of engineering students who scored FCD = x = 0.2 lakhs

In 2013, The number of students who graduated in engineering = 11.9% of 22 = 2.618 lakhs

percent of the engineering students had scored FCD

0.2  × 100 = 7.64%
2.618

Hence, option A is correct.

25% of the students who graduated in between 2012 and 2017 had applied for SBI clerk 2017 examination but only 10% of them had cleared prelims. It was observed that 65% of those who had cleared prelims had bought SMARTKEEDA practice set then find how many of the students had bought SMARTKEEDA practice sets? (students, who cleared prelims exam were only those who graduated in between 2012 and 2017) 
» Explain it
E
Total number of students, who graduated in between 2012 and 2017 = 16 + 22 + 24 + 25 + 32 + 28 = 147 lakhs 
 
Number of students who had applied for SBI clerk 2017 examination = 25% of 147 lakhs = 36.75 lakhs 
 
Number of students who cleared prelims = 10% of 36.75 lakhs = 3.675 lakhs
 
Number of students who had bought SMARTKEEDA practice sets = 65% of 3.675 lakhs = 2.38875 lakhs 

Hence, option E is correct.
 
5
The ratio of number of students in 2017 to that of in 2018 is likely to be 4 : 7 and the percentage share of students who will be graduated in finance is likely to increase by 9% then how many more students will be graduated in finance stream? 
» Explain it
A
Number of students in 2017: Number of students in 2018 = 4 : 7
 
Assume, number of students in 2017 = 4x and, the number of students in 2018 = 7x
 
According to the question, number of students in 2017 = 4x = 28 lakhs
 
So, the value of x = 7 lakhs 
 
Percentage share of students who graduated in Finance stream in 2017 = 9.9% = 9.9% of 28 = 2.772 lakhs 
 
the number of students in 2018 = 7x = 7 × 7 = 49 lakhs 
 
according to the question, the percentage share of students who will be graduated in finance is likely to increase by 9% = (9 + 9.9) % = 18.9% 
 
In 2018, The number of students, who graduated in finance stream = 18.9% of 49 = 9.261 lakhs 
 
Number of more students who will be graduated in finance stream in 2018 = (9.261 – 2.772) lakhs = 6.489 lakhs 

Hence, option A is correct.
