Annuity = 200 000 / (F / A, 10%, 5) = 32 760.03

What is 2500 + x = 1000 + 2x x

2500+x=1000+2x
2500-1000=2x-x
x=1500

There are () four digits within 10000? A.9000 b.1001 c.990 d.9001

A.9000
Three digit maximum = 999
There are 999
Ten thousand is five figures
4 digits = 1000-999-1 = 9000

What is the result of 1 / (1000 + 2) (1000 + 3) + 1 / (1001 + 2) (1001 + 3) +... + 1 / (2000 + 2) (2000 + 3) + 1 / (2001 + 2) (2001 + 3)

1/1002-1/1003+1/1003-1/1004+1/1004-...+1/2003-1/2004
All of them are out of date
It is equal to 1 / 1002-1 / 2004 = 1 / 2004
