Step 1: Reframe drop-outs as a "conversion rate" instead.
Rather than working with the drop-out percentage directly, it helps to work with the opposite quantity, the CV-posting rate (CVs posted divided by Registrations), since a higher conversion rate means a lower drop-out rate, and vice versa.
Step 2: Find the Managerial conversion rate for both years.
2004: $15{,}389/19{,}236 \approx 0.800$, so about 80% converted (20% dropped out). 2005: $40{,}763/45{,}292 \approx 0.900$, so about 90% converted (10% dropped out). Conversion rose from 80% to 90%, which means the drop-out rate fell from 20% to 10%. This confirms Statement X is true.
Step 3: Find the Technical conversion rate for 2005.
$60{,}133/63{,}298 \approx 0.950$, so about 95% of Technical registrants converted to CV-posters in 2005, meaning only about 5% dropped out.
Step 4: Compare the two 2005 drop-out rates.
Technical's drop-out rate (about 5%) is lower than Managerial's (about 10%) in 2005. Statement Y claims Technical's rate was higher, which is the opposite of what the numbers show, so Statement Y is false.
Step 5: Final Answer.
Only Statement X turns out to be correct.
\[ \boxed{\text{Only [X] is True}} \]
