Answer: D

Let the rate of each machine be r. Thus we have to find out the value of \(5\cdot r \cdot x\). Thus, it is sufficient to find the value of \(r \cdot x\).

Statement 1 states that \(3 \cdot r \cdot 2x= 72000\). No need to calculate anything, as we know the value of \(r∗x\). Sufficient \(\Large{\color{green}\checkmark}\)

Statement 2 states that \(2∗r∗x = 24000\). Just as above, Sufficient \(\Large{\color{green}\checkmark}\)

Therefore, D
