Step-by-step explanation:

Percentage of custom duty = 30%

Amount of custom duty = 9000 rupees

x = value of the item which is being imported

30% of x = 9000 rupees

30/100 * x = 9000

0.3 * x = 9000

0.3x = 9000

x = 9,000/0.3

x = 30,000 rupees

x = value of the item which is being imported = 30,000 rupees
