We know that, Discounted value % = 100% - Discount %.

Name of the persons	Repairing cost (in ₹)	Discount %	Discounted value %	Discounted value
A	5,500	30	70	$\dfrac{70}{100}$ x 5,500 = 3850
B	6,250	40	60	$\dfrac{60}{100}$ x 6,250 = 3750
C	4,800	30	70	$\dfrac{70}{100}$ x 4,800 = 3360
D	7,200	20	80	$\dfrac{80}{100}$ x 7,200 = 5760
E	3,500	40	60	$\dfrac{60}{100}$ x 3,500 = 2100
Total				18820

GST = 18%.

GST = $\dfrac{18}{100} \times 18820$ = ₹3387.60

Total money = ₹18820 + ₹3387.60 = ₹22207.60

Hence, the total money received by mechanic = ₹22207.60
