Answer 2

==================================

$\underline\bold{\huge{ANSWER \: :}}$

==================================

Let the present value of land or car be V.

Let the value of land (after uniform growth), and the car (after depreciation) be v.


1⃣ FOR LAND :-

V = Rs. 180000
v = ?
r = 30% (growth)
n = 3 yeas.



Now, v = V ( 1 + r/100)³

=> v = Rs.(180000 × (13/10)³)

=> v = Rs. 395460



2⃣ FOR CAR :-

V = Rs. 320000
r1 = 20% (depreciation)
r2 = 15% (depreciation)
r3 = 15% (depreciation)


Now, v = V (1 - r1/100) (1 - r2/100) (1 - r3/100)

=> v = Rs. (320000×(4/5)×(17/20)×(17/20))

=> v = Rs. 184960


SO, The original cost of land and car

= Rs. (180000+320000)

= Rs. 500000


SIMILARLY, New cost of land and car

= Rs. (395460+184960)

= Rs. 580420


ULTIMATELY, The actual profit

= Rs. (580420 - 500000)

= Rs. 80420 [REQUIRED ANSWER]
