Hints: Finding fractiles from the integrated hazard rate

To solve the problem you need to remember the relation between the (integrated) hazard rate and the survival function. In ABG this is discussed in Section 1.1.2. The derivation of this relation is also discussed in the video "Survival function and hazard rate", see link at the bottom of this page.
