Study the following graph carefully and answer the questions given below:

Distribution of candidates who were enrolled for MBA entrance exam and the candidates (out of those enrolled) who passed the exam in different institutes:

What is the ratio of candidates who passed to the candidates who enrolled from institute P?

A.

9 : 11

B.

14 : 17

C.

6 : 11

D.

9 : 17

Correct answer is C

Required ratio = ( (18% of 5700)/(22% of 8550) ) = ( (18 x 5700)/(22 x 8550) ) = 6/11

Study the following graph carefully and answer the questions given below:

Distribution of candidates who were enrolled for MBA entrance exam and the candidates (out of those enrolled) who passed the exam in different institutes:

What is the percentage of candidates passed to the candidates enrolled for institutes Q and R together?

A.

68%

B.

80%

C.

74%

D.

65%

Correct answer is B

Candidates passed from institutes Q and R together = [(13% + 17%) of 5700]

= 30% of 5700.

Candidates enrolled from institutes Q and R together = [(15% + 10%) of 8550]

= 25% of 8550.

Therefore Required Percentage = ( (30% of 5700)/(25% of 8550) x 100 ) %

= ( (30 x 5700)/(25 x 8550) x 100 ) % = 80%

13.

Study the following graph carefully and answer the questions given below:

Distribution of candidates who were enrolled for MBA entrance exam and the candidates (out of those enrolled) who passed the exam in different institutes:

The number of candidates passed from institutes S and P together exceeds the number of candidates enrolled from institutes T and R together by:

A.

228

B.

279

C.

399

D.

407

Correct answer is C

Required difference = [(16% + 18%) of 5700] - [(8% + 10%) of 8550]

= [(34% of 5700) - (18% of 8550)]

= (1938 - 1539)

= 399

14.

Study the following graph carefully and answer the questions given below:

Distribution of candidates who were enrolled for MBA entrance exam and the candidates (out of those enrolled) who passed the exam in different institutes:

Which institute has the highest percentage of candidates who passed to the candidates enrolled?

A.

Q

B.

R

C.

V

D.

T

Correct answer is B

The percentage of candidates passed to candidates enrolled can be determined for each institute as under:

(i) P = [ ( (18% of 5700)/(22% of 8550) ) x 100 ] % = [ (18 x 5700)/(22 x 8550) x 100 ] % = 54.55%

(ii) Q = [ ( (17% of 5700)/(15% of 8550) ) x 100 ] % = 75.56%

(iii) R = [ ( (13% of 5700)/(10% of 8550) ) x 100 ] % = 86.67%

(iv) S = [ ( (16% of 5700)/(17% of 8550) ) x 100 ] % = 62.75%

(v) T = [ ( (9% of 5700)/(8% of 8550) ) x 100 ] % = 75%

(vi) V = [ ( (15% of 5700)/(12% of 8550) ) x 100 ] % = 83.33%

(vii) X = [ ( (12% of 5700)/(16% of 8550) ) x 100 ] % = 50%.

Highest of these is 86.67% corresponding to institute R.

A.

50%

B.

62.5%

C.

75%

D.

80%

Correct answer is C

Required percentage = ( (9% of 5700)/(8% of 8550) x 100 ) % = ( (9 x 5700)/(8% of 8550) x 100 ) % = 75%
