The house could be sold between £ 77,000 and £ 79,500

Step-by-step explanation:

Cost of the house = £ 55,000

40% profit on the amount paid for the house = 40% * 55,000 = 0.4 * 55,000 = £ 22,000

Suggested price with at least 40% profit = £ 55,000 + £ 22,000

Suggested price with at least 40% profit = £ 77,000

Properties price on the same street:

Property 1 £75,000

Property 2 £80,000

Property 3 £83,500

Mean of these prices = (75,000 + 80,000 + 83,500) / 3

Mean of these prices = 238,500 / 3

Mean of these prices = £ 79,500

Therefore the price could be between  £ 77,000 (40% profit on the amount paid for the house 10 years ago) and £ 79,500 (the mean price of the properties currently for sale on the same street)
