Answer:-E

Since each day has 24 hours, it is a good idea to divide 253 by 24 to find the number of complete 24-hour intervals in 253 hours and the number of hours remaining after the 24-hour intervals have been accounted for. When 253 is divided by 24, the quotient is 10 and the remainder is 13. The 10 complete 24-hour intervals tell you that 10 days, or one full week plus 3 days, go by, bringing you to Tuesday at 4:00 p.m. The 13 additional hours take you into the next day, Wednesday. The 253 hours will end at 5:00 a.m. on Wednesday.

Re:Percentages 2 Months, 3 Weeks ago Karma: 0  
The answer is 8 %

Every 3 minutes , 4 liters ..i.e....80 liters in an hour ... [ there are 60 minutes in each hour ..therefore ...there are 20 '3 minutes" in each hour....which shows that @ 4 lts/3mins ...20 * 4 = 80 liters...]
since there are 2 hours... 2 * 80 liters = 160 liters

total volume of the tank is 2000 liters...and 160 is filled ...therefore 8 % is filled [ 160/2000 * 100 ]
