Answer 1

Answer:

Step-by-step explanation:

6) if a sales tax on a purchase worth Rs 60 is Rs 4.20

Purchase  = Rs 60

Sale Tax = 4.2 Rs

Sale Tax %  = (4.2/60) * 100 = 42/6 = 7 %

sales tax on a purchase worth Rs 150

Purchase  = Rs 150

Sale tax = 7 %

Sale Tax = (7/100) * 150  = 7 * 15/10   = 105/10  = 10.5 Rs

Rs 10.5 is sales tax on  a purchase worth Rs 150

8) 3 cm = 120 km

1 cm = 40

10 cm = 10 x 40

10 cm = 400 km
