# Memory Based Data Interpretation: SBI PO Prelims 2017

Memory Based Data Interpretation SBI PO Prelims 2017

Directions (1 – 5): Study the following table carefully and answer the questions that follow:

The table shows the number of females in different departments of an organization along with the ratio of number of males to females in respective departments. 1. Females in departments B and C make what percent of total employees in these two departments?
A) 45.18%
B) 38.81%
C) 34.76%
D) 48.31%
E) 42.24%
Option D
Solution:

For A: 4/13 * x = 1080, so total employees in dept. A = x = 3510
For B: 5/7 * x = 950, so total employees in B = x = 1330
Similarly, in C = 3120, D = 1320, E = 270
So required % = (950+1200)/(1330+3120) * 100 = 48.31%
2. What is the total number of males in departments A and E?
A) 3460
B) 3540
C) 3680
D) 3870
E) 3580
Option E
Solution:

Total employees in dept. A = 3510, so males = 3510 – 1080 = 2430
Total employees in dept. E = 2070, so males = 2070 – 920 = 1150
So required total = 2430+1150 = 3580
3. If 5% males and 10% females in department D are post graduates, then find the number of post-graduate employees in the same department.
A) 114
B) 108
C) 86
D) 94
E) 90
Option B
Solution:

In D total employees = 1320, females = 840, so males = 480
So post-graduate males = 5% of 480 = 24
And post-graduate females = 10% of 840 = 84
So required total = 24+84 = 108
4. Females in department A and B together are what percent more/less than males in departments C and D together?
A) 12.47%
B) 17.67%
C) 14.34%
D) 15.42%
E) 16.76%
Option D
Solution:

Females in A and B = 1080+950 = 2030
Males in C and D = (3120-1200) + (1320-840) = 2400
So required % = (2400-2030)/2400 * 100 = 15.42%
5. If 10% males and 5% females from department E gets shifted to department B, find the new ratio of females to males in department B.
A) 330 : 163
B) 332 : 165
C) 254 : 103
D) 312 : 178
E) 296 : 108
Option B
Solution:

5% of females in E = 5% of 920 = 46
5% of males in E = 10% of 1150 = 115
Females in B = 950, so new number of females = 950+46 = 996
Males in B = 380, so new number of males = 380+115 = 495
So required ratio is 996 : 495 = 332 : 165

Directions (6 – 10): Study the following line chart carefully and answer the questions that follow: 1. Find the difference between the number of students in school B in years 2012 and 2013 together and number of students in school A in years 2012 and 2014 together?
A) 1700
B) 1800
C) 1500
D) 1600
E) None of these
Option D
Solution:

Required difference = (3200+3000) – (2400+2200) = 1600
2. What is the percentage increase in number of students in school B from year 2011 to year 2014?
A) 34.35%%
B) 28.75%
C) 31.35%
D) 30.77%
E) 33.25%
Option D
Solution:

Required % = (3400-2600)/2600 * 100 = 30.77%
3. If in year 2016, the number of students in both schools increased by 10% with respect to year 2014, then find the difference between the number of students in both schools in years 2015 and 2016.
A) 120
B) 140
C) 125
D) 136
E) 144
Option B
Solution:

In A and B in 2016 = 110/100 (2200+3400) = 6160
In A and B in 2015 = 2800+3500 = 6300
So required difference = 6300 – 6160 = 140
4. In year 2013, in both schools the ratio of boys to girls is 3 : 2. Number of boys in both schools in 2013 is what percent of the total number of students in both schools in the same year?
A) 65%
B) 55%
C) 62%
D) 56%
E) 60%
Option E
Solution:

Number of boys in school A in 2013 = 3/5 * 2500 = 1500
Number of boys in school B in 2013 = 3/5 * 3000 = 1800
So required % = (1500+1800)/(2500+3000) * 100 = 60%
5. In how many years the number of students in both schools together is 12% less than the number of students in both schools together with respect to the previous year?
A) None
B) One
C) Two
D) Three
E) Four
Option C
Solution:

In 2012 = [(3200+2400) – (2000+2600)]/(2000+2600) * 100 = 21.74%
In 2013, there is a decrease in total students, so it is certainly less.
In 2014 = [(2200+3400) – (2500+3000)]/(2500+3000) * 100 = 1.81%
In 2015 = [(2800+3500) – (2200+3400)]/(2200+3400) * 100 = 12.5
