Accepted Solution

A:
Answer:£700,000Step-by-step explanation:Let's call x the original value of the house. Keeping in mind that[tex]7%=\frac{7}{100}[/tex]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[tex]x+\frac{7}{100}x = 749,000[/tex]Now we can solve the equation to find x:[tex]x+\frac{7x}{100}=749,000\\100x + 7x = 74,900,000\\107 x = 74,900,000\\x=\frac{74,900,000}{107}=700,000[/tex]So, the original value of the house was£700,000
