Neco 2022 Civic Education Question 46

The National Drug Abuse Survey of 2022 reported that the initial prevalence of illicit drug use among Nigerians aged 15\-24 was \(12\%\). The government introduced two successive intervention programmes. Programme A reduced drug use by \(30\%\) of the current users. After Programme A, a specialised high‑risk group, which originally constituted \(10\%\) of all drug users, was exempt from the next intervention. Programme B targeted the remaining users (excluding the high‑risk group) and reduced their usage by \(40\%\). Assuming the interventions affect only the users and no new users start, what is the final percentage of the 15\-24 age group that remains using drugs after both programmes? Give your answer to two decimal places.
