In which month percentage increase/decrease is maximum for other employees?
» Explain it
Percentage increase/decrease of different months for other employees-

Feb     —  40 - 33  × 100 = 17.5

March —  40 - 33  × 100 = 21.21

April    —  40 - 35  × 100 = 12.5

May     —  42 - 35  × 100 = 20

June   —  50 - 42  × 100 = 19.05

Clearly the maximum increase as it shows is in the month of March.

Hence, option B is correct.
How much Percentage increase in officers transfer from February 1997 & to March 1997?
