equation is x*1.2*.75=x*.95 so 5% lower

ha, can't multiply anymore - 1.2*.75 is actually .9 - 10% lower

1995-1996
say it was 100 in 1995 so, will be 120 in 1996
And 25% of 120 = 1/4th of 120=30
hence in 1997 => 90

1995 to 1997 10% less.

Ans: C

To do this question by equations:

1995: X
1996: (120/100) X = 1.2X
1997: (75/100) * (120/100) X = 0.9X

So answer is 10%, C.
