cistern is full, in how much time will it be emptied by the leak.​

Answer 1

Answer:

When there is no leakage A pipe can fill the cistern in = 10 hours In 1 hour without leakage A pipe can fill the cistern in = 1/10 hours When there is leakage cistern gets filled in = 12 hours In 1 hour, when there is leakage cistern gets filled in = 1/12 hours In 1 hour, due to leakage cistern gets filled to = 1/10 – 1/12 = (12-10)/120 = 2/120 = 1/60 part ∴ Due to leakage the cistern gets emptied in = 1/(1/60) = 60 hours.Read more on Sarthaks.com - https://www.sarthaks.com/667525/a-pipe-can-fill-a-cistern-in-10-hours-due-to-a-leak-in-the-bottom-it-is-filled-in-12-hours
