The least and highest value of the house before being rounded are £184999 and £175000 respectively.
The initial value of Sue's house before the increase is £205,000
£180,000 correct to 2 significant figures :
The greatest value of the house would be a sum in which the third significant figure is a value less than 5 and the succeeding values are highest
The least value of house would be a sum in which the third significant value is 5 and the succeeding values are lowest.
2.)
Let the price before the increase = p
- Price after increase = £219350
7% of p = 219350
(1+7%) × p = 219350
1.07p = 219350
p = 219350 / 1.07
p = £205,000
Therefore, the price of the house before the increase is p = £205,000
