There are two water drums in my house whose volumes are in the ratio 1 : 5. Every day the smaller drum is filled first and then the same pipe is used to fill the bigger drum. Normally by the time I return from my college i.e. at 1.30 p.m., the smaller drum would justbe full. But today I returned a little early and started drawing water from the well with the help of a bucket, poured one-third into thesmaller drum and the remaining into the bigger drum. I continued this till the smaller drum was filled. Immediately after that, I shifted the pipe into the bigger drum and went for lunch. Today if the bigger drum was filled in 12 minutes before its normal time, when wasthe smaller drum full?

Mona and Sona start simultaneously from two towns, P and Q, towards Q and P respectively at 8:00 a.m. R is a checkpost which is midway between P and Q. Both Mona and Sona turn back towards their respective starting points whenever they reach R and every time they reach their starting points they turn back and return to R. If the speeds of Mona and Sona are 45 km/hr and 60 km/hr respectively and PQ = 24 km, when will they reach R at the same time?
