Saras gas tank was 1515 full When full it holds 1616 gallons

Sara\'s gas tank was 1515 full. When full, it holds 1616 gallons of gas.
How many gallons of gas were in the tank?

Solution

I think there is something wrong in this question. With this given information it can\'t be solved.

If in first line it is 15.15% full then

total capacity of tank = 1616 gallons

then 15.15 % is

1616 * 15.15 / 100

= 244.824 gallons

If it is 15.15% full then there will be 244.824 gallons of gas in the tank.
