A network administrator is given the address block \(192.168.48.0/20\). Three departments need subnets for \(200\), \(50\) and \(10\) usable hosts respectively. Allocate subnets that minimise wasted addresses, and for each subnet provide (i) the subnet mask in dotted‑decimal form, and (ii) the first usable IP address.
