A.	Q
B.	R
C.	V
D.	T

Answer: Option B

Explanation:

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

(i) P = 18% of 5700 x 100 % = 18 x 5700 x 100 % = 54.55%.

22% of 8550 22 x 8550

(ii) Q = 17% of 5700 x 100 % = 75.56%.

15% of 8550

(iii) R = 13% of 5700 x 100 % = 86.67%.

10% of 8550

(iv) S = 16% of 5700 x 100 % = 62.75%.

17% of 8550

(v) T = 9% of 5700 x 100 % = 75%.

8% of 8550

(vi) V = 15% of 5700 x 100 % = 83.33%.

12% of 8550

(vii) X = 12% of 5700 x 100 % = 50%.

16% of 8550

Highest of these is 86.67% corresponding to institute R.

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

= (1938 - 1539)

= 399.
