Diberi bahawa ρ berubah secara songsang dengan q dan p =8 apabila q = 3.

Hitung nilai q apabila p= 6.

• 2

• 4

Answer explanation

Given that ρ varies inversely with q and p = 8 when q = 3. To find q when p = 6, we use the inverse variation formula ρ = kp, where k is a constant. So, when p = 8 and q = 3, k = ρ/p = 3/8. Substituting p = 6, we get q = ρ/k = 6 * (3/8) = 4. Therefore, the correct answer is 4.
