ok sir
type-9 question-2 at (A+B) you multiple 9*2 but they only does work together for 1hour so 9*1 is correct there🤘🏻 final time to empty the tank will come 1:10pm🤘🏻 thanks for your lectures you are awesome teacher.
Tap a fills a tank in 10 hours and b can fill it in 15 hours. both are opened simultaneously. sometimes later tap b was closed, then it takes total 8 hours to fill up the whole tank. after how many hours b was closed?
