Requirements for the years 91 and 92 = 190 + 325 = 515.
Production for the years 91 and 92 = 250 + 260 = 510
Required percentage = 5 / 510 = 0.98%
Production for the years 91 and 92 = 250 + 260 = 510
Required percentage = 5 / 510 = 0.98%

Percentage fall in Nifty: (1,285 – 1,265)/1,285
= 18/1,285 = 1.4 %,
hence 98.50 is the best answer.

784 (1 + x)4 = 2077.
By hit and trial we get x = 27 % (approximately).
The method to do this is: first find the multiplication factor, in this case it is 2,077/784 = 2.65.
We know that (1.25)4 = 2.44 so the answer must be > 25 %.

In 1992, (325 - 190) / 190 x 100 = 71%
In 1991, (190 - 60) / 60 x 100 = 216.6%
In 1994, (290 - 220) / 220 x 100 = 31.8%
1991 percentage increase in the requirement of flowers over the previous year is the maximum.
