The capacity of a jug is 3.5 l correct to the nearest 0.1 l. This places the volume of the jug between 3.50 l and 3.59 l

The capacity of a glass is 0.25 l correct to the nearest 0.01 l. This places the volume of a glass between 0.259 and 0.250 l

The maximum number of glasses that can surely be filled is equal to the whole number that lies just below 3.50/0.259.

3.50/0.259 = 13.51

The required value of the greatest number of glasses that can be surely filled is 13.

I have a problem... isn't this concerned with upper bounds and lower bounds?
