Answer:
a) Realized gain on the sale of land = Selling price – tax basis
=> $100,000 - $77,000 = $23,000
b) Gross profit percentage as per instalment sale method = Gross profit / Sales
=> $23,000/$100,000 = 0.23 or 23%
c) Recognized gain under instalment sale method = Cash collection x gross profit percentage
Year 1 => $10,000 x 23% = $2,300
Year 2 => $45,000 x 23% = $10,350
Year 3 => $45,000 x 23% = $10,350
