(a) For Component A,
Repairing cost = ₹ 5,000, Discount = 20%
Discount = $\frac{20}{100} \times 5000$ = ₹ 1,000
For Component B,
Repairing cost = ₹ 6,500, Discount = 30%
Discount = $\frac{30}{100} \times 6500$ = ₹ 1,950
Total discount = ₹ 1,000 + ₹ 1,950 = ₹ 2,950.
Hence, the total discount = ₹ 2,950.
(b) For Component A,
Cost after discount = ₹ 5,000 − ₹ 1,000 = ₹ 4,000
For Component B,
Cost after discount = ₹ 6,500 − ₹ 1,950 = ₹ 4,550
Total taxable amount = ₹ 4,000 + ₹ 4,550 = ₹ 8,550
GST = $\frac{18}{100} \times 8550$ = ₹ 1,539.
Hence, the total amount of GST = ₹ 1,539.
