Answer
The maximum dose of Aspirin is 0.6 g every 4 hours. In one day (24 hours), the maximum number of doses can be calculated as follows:
Number of doses in 24 hours:
rac{24 ext{ hours}}{4 ext{ hours}} = 6 ext{ doses}
Total maximum dose of Aspirin in one day:
6imes0.6extg=3.6extg
Next, we calculate the sodium intake:
For Aspirin, sodium in one tablet is 0.15 g, and the total sodium in one day is:
6imes0.15extg=0.9extg

Answer
The maximum dose of Paracetamol is 1.0 g every 6 hours. Similar to the previous calculation, the number of doses in one day is:
Number of doses in 24 hours:
rac{24 ext{ hours}}{6 ext{ hours}} = 4 ext{ doses}
Total maximum dose of Paracetamol in one day:
4imes1.0extg=4.0extg
Next, we calculate the sodium intake:
For Paracetamol, sodium in one tablet is 0.43 g, and total sodium in one day is:
4imes0.43extg=1.72extg

Answer
Now, we compare the total sodium intake from both medicines to the RDA of sodium, which is 2.4 g per day.
For Aspirin: 0.9 g (less than RDA)
For Paracetamol: 1.72 g (less than RDA)
Therefore, the journalist’s statement is not true for either of the medicines in Table 2.
