Ms Voyager was on her solo trip to Shimla. She boarded the local passenger bus called “Traveller” from “Summer Hill (SH)” stop and got off at “Old Shimla” (OS)”. In between there are five stations and she decided to take a note of the number of passengers who boarded and got off “Traveller”.
Also the price of ticket between two stations is equal to one plus the number of stations in between those two stations. For example the ticket price of one passenger from Summer Hill to the mall road is equal to Rs 3 and that of one passenger from Monkey Point to Old Shimla is Rs 5. When she got off the Traveller at Old Shimla Bus stand she had following information with her. Also no person got off the same stop at which he/she boarded.

The investors can invest in four mutual funds – ICICI, SBI, Kotak and HDFC, to buy stocks of these four companies. Not all the investors invested in the mutual funds every month but when they did, each person invested Rs.100 to any one of the four mutual funds in a month, not necessarily the same fund every month.
For each of the four funds, the number of people who invested in each of October, November and December was either equal to or one greater or one lesser than their corresponding numbers in the previous month. For example, if ‘n’ investors invested in the ICICI fund in October, then the number of investors who invested in the ICICI fund in November can be ‘n – 1’, or ‘n’ or ‘n + 1’.
