Question

The value of Hector's house has increased by 5%.

His house is now valued at £609 000
Work out the value of the house before the increase.

Answer 1

$580000

Explanation:

To find decrease we simply reverse the operations of increase

increase is x x 1.05 = 609000

x = 609000 / 1.05 = 580000 initial value

x= $580000

proof

580000 x 1.05 = 609000 new value
