Answer 1

Answer:

65 acres

Step-by-step explanation:

let first year he buy n acres of land

and second year he buy n+x acres of land

third year. n+2x

fourth year. n+3x

means 8th years n+7x = 45

and 5th year. n+4x=30

solving we get n= 10 and x=5

means in last year i.e. 12th year he will buy n+11x

which comes out 10+11*5=10+55=65
