Answer 1

Answer:

(a) 8%

(b) 396000

Step-by-step explanation:

Income in 2010 = 360000

Income in 2011 = 388800

(a)

→ The increased income = 388800 - 360000 = 28800

→ The percentage increase in his annual income in 2010 is 28800/360000 = 8 %

(b)

Income in 2010 was 10% less than that in the previous year, year 2009

→ Income in 2009 - income in 2010 = 10% In come in 2010

→ Income in 2009 - 360000 = 10%*360000

→ Income in 2009 = 360000 + 36000 = 396000
