Answer 1

Answer:

91.3125 %

Step-by-step explanation:

Let the value of a property be n.

in first year : n + 25/100n = n + 1/4n = 5/4n

second year : 5/4n + 25/100 * 5/4n

= 5/4n + 5/16n = 25/16n

third year : 25/16n + 25/100 * 25/16n

= 25/16n + 25/64n = 125/64n

percentage increase :

(125/64n - n)/n * 100 = (125 - 64)n/64n * 100%

61n/64n * 100%

= 61/64 * 100%

= 91.3125 %
