A bottle of syrup contains 45 ml with a strength of 125 mg/5 ml. If a child is prescribed 250 mg twice daily for 5 days, how many bottles are required?

Correct option is B

Understood. Here is the syrup bottle calculation again, provided in a plain text format without mathematical symbols:

Step 1: Calculate the volume of syrup per dose
The syrup strength is 125 mg in 5 ml. By dividing 125 by 5, we find that each 1 ml contains 25 mg of medicine.
To get the prescribed 250 mg dose, we divide 250 by 25, which equals 10 ml per dose.

Step 2: Calculate the total volume needed for the course
The child takes 10 ml twice a day, which is 20 ml per day.
Over a 5-day period, 20 ml multiplied by 5 days equals a total of 100 ml needed.

Step 3: Calculate the number of bottles
Each bottle contains 45 ml. To find out how many bottles make up 100 ml, we divide 100 by 45, which is approximately 2.22 bottles.

Since you cannot buy a partial bottle and the child needs the full 100 ml, you will need to get 3 bottles
