Answer 1

Answer:

84%

56%

Step-by-step explanation:

Volume of petrol = 60 l

Used petrol = 30% of 60 l = 0.3*60 l= 18 l

Remaining petrol = 60 l - 18 l = 42 l

1) Full volume of tank is 50 l

Filled volume is 42 l

Fill percent = 42/50 * 100%= 84%

2) Usage of petrol is 2.8 /day

Usage after 10 days = 2.8 l/day * 10 days= 28 l

Usage percent after 10 days = 28/50 *100% = 56%
