Read the passage below and solve the questions based on it.
There are four friends Sharat, Chandra, Mayank and Sid living in the same village of Bhagalpur. Once Sharat had nothing to eat, so, Chandra, Mayank and Sid collected their rotis and gave a part of their rotis to Sharat. It was later found that the number of rotis given by Chandra is one more than the rotis given by Mayank, and the number of rotis given by Mayank is one more than the rotis given by Sid. Now Sharat was required to pay the cost of rotis in the ratio of the rotis contributed by all three of them. It was found that Chandra should get twice as much money as Mayank. Price of one roti = Rs 5.(All the values, number of rotis and money are in integers.)
How many rotis were consumed by all of them?
