**ANSWERS**:

**1.**

**Answer**(B): The differences between the

percentages of candidates qualified to appeared for the give pairs of years

are:

For 1994 and 1995 = 50 – 30 = 20.

For 1998 and 1999 = 80 – 80 = 0.

For 1994 and 1997 = 50 – 30 = 20.

For 1997 and 1998 = 80 – 50 = 30.

For 1999 and 2000 = 80 – 60 = 20.

Thus, the maximum difference is

between the years 1997 and 1998.

between the years 1997 and 1998.

**2.**

**Answer**: (

**D**)

The graph gives the data for the

percentage of candidates qualified to appeared and unless the absolute values

of number of candidates qualified or candidates appeared is know we cannot

compare the absolute values for any two years. Hence, the data is inadequate to

solve this question.

**3.**

**Answer**: (

**C**)

The number of candidates appeared in

1998 be x.

1998 be x.

Then, 80% of x = 21200

è x = (21200 *100)/(80) = 26500( Required number)

**4.**

.

**Answer**: (

**D**)

The total number of candidates

qualified in 1996 and 1997 together, cannot be determined until we know at

least, the number of candidates appeared in any one of the two years 1996 or

1997 or the percentage of candidates qualified to appeared in 1996 and 1997

together. Hence, the data is inadequate.

qualified in 1996 and 1997 together, cannot be determined until we know at

least, the number of candidates appeared in any one of the two years 1996 or

1997 or the percentage of candidates qualified to appeared in 1996 and 1997

together. Hence, the data is inadequate.

**5.**

**Answer**:

(

**C**)

The number of candidates qualified in

1999 = (80% of 26500) = 21200.

1999 = (80% of 26500) = 21200.

Number of candidates qualified in 2000

= ( 33500 – 21200 ) = 12300.

= ( 33500 – 21200 ) = 12300.

Let the number of candidates appeared

in 2000 be x.

in 2000 be x.

Then, 60% of x = 12300

x = ( 12300 x 100)/(60) =

20500.

20500.

**6.**

**Answer**(

**D**)

Required number = (17% of

27300) + (14% of 24700)

27300) + (14% of 24700)

= 4641 + 3458

= 8099

**7.**

**Answer**: (

**D**)

Required ratio =(21% of

24700)/ (14% of 27300)

24700)/ (14% of 27300)

=(21 x 24700)/(14 x 27300)

= 19/14

= 19/14

**8.**

**Answer**: (

**B**)

Students of institute M at

graduate level= 17% of 27300 = 4641.

graduate level= 17% of 27300 = 4641.

Students of institute S at

graduate level = 14% of 27300 = 3822.

graduate level = 14% of 27300 = 3822.

Total number of students

at graduate in institutes M and S = (4641 + 3822)

at graduate in institutes M and S = (4641 + 3822)

= 8463.

**9.**

**Answer**: (

**D**)

Required ratio = (21% of

24700)/ (13% of 27300)

24700)/ (13% of 27300)

= 19/13

**10.**

**Answer**: (

**C**)

Required number = (15% of

24700) + (12% of 24700)

24700) + (12% of 24700)

= 3705 + 2964

= 6669.
