Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 18.18%.
The value of an Apple laptop depreciated from Rs. 1,33,100 to Rs. 72,900 in 3 years.
Depreciated value = Initial value × (1 - r/100)3
72900 = 133100 × (1 - r/100)3
(9/1)3 = (1 - r/100)3
9/11 = (1 - r/100)
-2/11 = -r/100
r = 200/11
r = 18.18%
