­The child's dosage is given by \(d = \frac{y+1}{24}\)­,

Yet everyone is doing :Child's dose = = d*(\(\frac{y+1}{24}\)­), why?­

Infact according to original eqn : \(800 = \frac{9}{24}\)­, which is not possible.

carcass, is there a typo. Thank you.­

Fixed. Thank you. = instead of *.....but of course the formula must have *. Just a mismatch. My bad

d=800 and y=8. These are given

Put into the formula

\(800 \times \dfrac{8+1}{24}\)

Calculate

300 is the answer­
