The total income of Mr. Sakib in the years 2003, 2004, and 2005 was Taka 36, His income increased by 20% each year. What was his income in 2005?

A 1500

B 14400

C 16450

D 12350

Solution

Correct Answer: Option B

Income in 2003=x

Income in 2004 =.20x+x

income in 2005=(x+.20x)+.20(x+.20x)

Now,x+.20x+x+x+.20x+.20x+.04x=36400

x=10000

income in 2005=14400
