Question

The value of Zlatan's house has increased by 7%. his house is now valued at £749,000. work out the value of the house before the increase.

Answer 1

Answer:

£700,000

Step-by-step explanation:

Let's call x the original value of the house. Keeping in mind that

$7%=\frac{7}{100}$

We have that when the value of the house increases by 7%, the new value is £749,000. This condition can be re-written as

$x+\frac{7}{100}x = 749,000$

Now we can solve the equation to find x:

$x+\frac{7x}{100}=749,000\\100x + 7x = 74,900,000\\107 x = 74,900,000\\x=\frac{74,900,000}{107}=700,000$

So, the original value of the house was

£700,000
