Face value of each share = Rs 100
Market value of each share = Rs 1,200
Number of shares purchased = 100
(1) Net amount paid for 100 shares = Market value of each share × Number of shares purchased = Rs 1,200 × 100 = Rs 1,20,000
(2) Rate of brokerage = 0.3%
∴ Brokerage paid on sum invested = 0.3% of Rs 1,20,000 = = Rs 360
(3) GST paid on brokerage = 18% of Rs 360 = = Rs 64.80
(4) Total amount paid for 100 shares
= Net amount paid for 100 shares (or Sum invested) + Brokerage paid on sum invested + GST paid on brokerage
= Rs 1,20,000 + Rs 360 + Rs 64.80
= Rs 1,20,424.80
