From option (I) ,
Sum = Rs. 80,000
So, total amount = 80,000 X (1.15) 2 X (1.2) 2 = Rs. 152352 ≠155022
So, (I) is not true.
Option (II)
Sum = Rs. 60,000
So, total amount = 60,000 X (1.15) 3 X (1.2) 1 = Rs. 109503 ≠112382
So, (II) is not true.
Option (III)
Sum = Rs. 90,000
So, total amount = 90,000 X (1.15) 1 X (1.2) 3 = Rs. 178848
So, (III) is true.
