Lemme also drop mine. Btw, its off head assumption, but its a lil bit realistic.
Assuming that the rate of outflow of water from a tank of capacity 2500 dm³ as a result of a hole at the base of the tank is directly proportional to the volume of water in it at each point in time, if it takes 10 hours for the water to drop from full capacity to 1%, find
A) how long it'll take to drop to 10%
B) the volume of water left after 1 hour
C) the volume of water left after 9 hours
In short in a tabular form, show the % of amount left for each of the first ten hours.
*the solution is in the thinking*

The religion section has suffered a lot from a lack of moderators/moderation. Little wonder the place is such a ghost town often, with lacklustre threads and more of its participants migrating to politics section, family and even romance. The OP asked a valid question and DIRECTED those questions. All we have here are a bunch of boys displaying their immaturity like they're the first set of unbelievers on public forum. Please, you guys should learn to exercise some restraint and good behavior instead of just occupying space with useless chats and rants.
