**Directions (1-5) : In the table data is given about passed and failed students of five colleges. Some data are given and some are missing. Study the table carefully and answer the related questions given below.**

- Number of failed students is what percent of number of passed students in school D ?

A) 20%

B) 80%

C) 50%

D) 60%

E) 90%

View Answer

**Option B**

**Solution:**

Number of students in school D = 324000 * (80/360) = 72000

Number of passed students in school D = 72000 *(5/10) = 36000

Number of failed students in school D = 72000 * (4/10) = 28800

Required Percentage = (28800 *100 )/36000 = 80%

- How much percent of students are absent from all six schools ?

A) 15.06%

B) 13.26%

C) 13.05%

D) 14.88%

E) 17.47%

View Answer

**Option C**

**Solution:**

Number of students in school A = 324000 * (60/360) = 54000

Number of absent students in school A = 54000 *(1/6) = 9000

Number of students in school B = 324000 *(48/360) = 43200

Number of absent students in school B = 43200 *(1/8) = 5400

Number of students in school C = 32400 *(52/360) = 46800

Number of absent students in school C = 46800 *(2/13)= 7200

Number of students in school D = 32400 *(80/360) = 72000

Number of absent students in school D = 72000 *( 1/10)= 7200

Number of students in school E = 324000 *(45/360) = 40500

Number of absent students in school E = 40500 *(1/9) = 4500

Number of students in school F = 324000 *(75/360) = 67500

Number of absent students in school F = 67500 *(2/15) = 9000

Required Percentage = (9000 + 5400 + 7200 + 7200 + 4500 +9000) *100 / 324000 = 13.05%

- What is the respective ratio of number of students who attended exam from school C and school F ?

A) 55 :64

B) 52 : 45

C) 44:65

D) 49:51

E) None of these

View Answer

**Option C **

**Solution:**

Number of students in school C = 46800

Number of absent students in school C = 7200

Number of present students in school C = 46800 – 7200 = 39600

Number of students in school F = 67500

Number of absent students in school F = 9000

Number of present students in school F = 67500 – 9000 = 58500

Required ratio = 39600 : 58500 = 44 : 65

- What is the difference between passing percentage of students in school B and school E ?

A) 6.9%

B) 7.2%

C) 6.2%

D) 6.5%

E) None of these

View Answer

**Option A**

**Solution:**

Passed % of students in school B = (3/8) * 100 = 75/2

Passed % of students in school E = (4/9) * 100 = 400 /9

Required difference =( 400 / 9) – (75/2 ) = 125/18 = 6.9%

- Number of passed students is how much percent more /less than the number of failed students from all schools ?

A) 15.47%

B) 13.45%

C) 14.38%

D) 15.74%

E) 13.66%

View Answer

**Option C**

**Solution:**

Number of passed students in school A = 324000 * (60/360)*(3/6) = 27000

Number of failed students in school A = 32400 *(60/360)*(2/6) = 18000

Number of passed students in school B = 324000 * (48/360)*(3/8)=16200

Number of failed students in school B = 324000 * (48/360)*(4/8)=21600

Number of passed students in school C = 324000 * (52/360)*(6/13)=21600

Number of failed students in school C = 324000 * (52/360)*(5/13) = 18000

Number of passed students in school D = 324000 * (80/360)*(5/10)=36000

Number of failed students in school D = 324000 * (80/360)*(4/10)=28800

Number of passed students in school E = 324000 * (45/360)*(4/9)=18000

Number of failed students in school E = 324000 * (45/360)*(4/9)=18000

Number of passed students in school F = 324000 * (75/360)*(7/15)=31500

Number of failed students in school F = 324000 * (75/360)*(6/15)=27000

Required percentage = [No. of passed students of all schools – No. of failed students of all schools]/ no. of failed students of all schools

= [(150300 – 131400 )/131400]*100 = 14.38%

**Directions (6-10): In the pie- chart data is given about the number of students who are studying in different schools in year 2016. In the table data is given about the passed, failed and absent students. Study the data carefully and answer the related questions given below.**

- What is the ratio of the number of boys who failed and the number of girls who failed in college A?

A) 10 : 13

B) 15 : 16

C) 12 : 18

D) 18 : 16

E) None of these

View Answer

**Option B**

Solution:

Total number of boys in college A = 3500 * (100 /(100 – 30)) = 5000

Number of boys who failed in college A = 5000 – 3500 = 1500

Number of girls who passed in college A = 2400

Total number of girls in college A = 2400 * (100/60) = 4000

Number of girls who failed in college A = 4000 – 2400 = 1600

Required ratio = 1500 : 1600 = 15 : 16

- Number of girls who passed is what percent of the number of failed students in college D ?

A) 48.24%

B) 45.78%

C) 47.62%

D) 49.52%

E) 42.67%

View Answer

**Option C**

Solution:

Total number of boys in college D = 7000 * (100/ 100 -30) = 10000

Total number of girls in college D = 5000 * (100 / 100 – 40) = 12500

Total number of students in college D = 10000 + 12500 = 22500

Total number of failed students in College D = 22500 – (7000+5000)

= 10500

Required percentage = (5000/ 10500 ) * 100 = 47.62%

- What is the difference between the number of boys in E and the number of girls in C?

A) 4000

B) 10000

C) 8000

D) 6000

E) 11000

View Answer

**Option A**

Solution:

Number of students in E = 13000 * (100/100 -50) = 26000

Number of girls in E = 6000 * (100/100-40) = 10000

Number of boys in E = 26000 – 10000 = 16000

Number of students in C = 12000 * (100 / 100- 40) = 30000

Number of boys in C = 9000 * (100/100-50) = 18000

Number of girls in C = 30000 – 18000 = 12000

Required difference = 16000 – 12000 = 4000

- Number of boys is what percent of the number of students in college B ?

A) 52.74%

B) 53.55%

C) 45.78%

D) 50.18%

E) 53.12%

View Answer

**Option E**

Solution:

Total number of students in college B = 8000 *(100/50) = 16000

Total number of girls in college B = 3300*(100/100-56) = 7500

Total number of boys in college B = 16000 – 7500 = 8500

Required percent = (8500*100)/16000 = 53.12%

- What is the number of all students of college A and D ?

A) 40000

B) 35000

C) 56000

D) 31500

E) 42000

View Answer

**Option D**

Solution:

Number of boys in college A = 5000

Number of girls in college A = 4000

Total number of students in college A = 9000

Number of boys in college D = 10000

Number of girls in college D = 12500

Total number of students in college D = 22500

Total number of students in both the colleges = 9000+22500 = 31500

Mam I think there is something wrong in 1st di

refresh

wrong code pasted

Ma’am wrong code for what

at backend

refresh once

Mam, question is interchanged not all of them but the initial ones. Please redress it. Thanks for the question set.

It was changed already

Might be you had opened page before it was changed

refresh once

How you guys solved 1st Di from where I can get same data that you mentioned in solution

what are you not getting ?

Actually at that time questions have solution of another question

now everything is ok na ?

Yes ma’am

tyyy mam

ty nice qs

@Mod correction req.

DI 1= ratio for F is 7 : 6 : 1

so for qsn 2nd= >>Number of absent students in school F = 67500 *(2/15) = 9000<< It cant be 2/15….it must be 1/14

It wud be 7:6:2

@mod

di-1

i think ratio of F be 7 : 6 :2

do check

Tks

Thanx a lot dear nice q….

8/10 nice di thnk u

Any trick to attempt 2nd question??

take only degrees not values like

absent values=10+6+8+8+5+10=47

total=360

absent%=47/360 *100 =13.05%

use this in all ques u solved it In 4-5 min easily
