Answer 1

Given:

The value of a house is 600,000 in 2005.

It increased by 25% in 2006 and 10% in 2007 but dropped by 15% in 2007.

To find:

The value of the house in 2008.

Solution:

We have,

Value of house in 2005 = 600,000

It increased by 25% in 2006.

Value of house in 2006 =
`600,000+(25)/(100)600,000`

=
`600,000+150,000`

=
`750,000`

It increased by 10% in 2007

Value of house in 2007 =
`750,000+(10)/(100)750,000`

=
`750,000+75,000`

=
`825,000`

But it dropped by 15% in 2007.

Value of house in 2008 =
`825,000-(15)/(100)825,000`

=
`825,000-123,750`

=
`701,250`

Therefore, the value of the house in 2008 is 701,250.
