A
Rs.20,000

B
Rs.15,000

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.

Hence, the correct option is (b).

The total number of candidates qualified in 1999 and 2000 together was 33,500 and the number of candidates appeared in 1999 was 26,500. What was the number of candidates in 2000?

A

Number of candidates qualified in 2000 = ( 33,500 - 21,200 ) = 12,300.

Let the number of candidates appeared in 2000 be x.

Then, 60% of x = 12,300
