Question 2:

A pipe can fill a cistern in $25 \mathrm{hr}$ find the part of tank filled in $5 \mathrm{hr}$.

Question 3:

Tap A can fill an empty tank in $10 \mathrm{hrs}$. Tap B can fill the same empty tank in $12$ hrs and tap 'C' can empty the full tank in $20$ hrs. If tap C is opened for entire period, tap A and tap B are opened in alternate hours starting with A, then tank will be full in hrs?
