lb equals 224 kg

    Here weight of patient is 80 kg or 176 lb and
    Daily dose of drug is 2 mg/kg

    Daily dose
    = `80 \quad kg × 2 \quad (mg)/(kg) = 160 \quad mg `

    weight of the capsule is 80 mg

    patient needs
    = `(160)/(80)`
    = 2 capsules/day

    for 16 weeks of therapy patient needs
    ` (2 \quad c a p s u l e s )/(day)× (7\quad day)/(week) × 16 \quad weeks `
    = 224 capsules Ans.
