Natural gas once extracted from a source is purified for commercial use at natural gas plants. From gas plants it is pumped to various destinations through pipelines. There are pumping stations, at intermediate places to maintain recommended pressure in the pipelines. The pumping stations do not produce or process any natural gas. They pump out exactly the quantity they receive from plants or other pumping stations.

The following figure depicts a network gas pipelines. The circles denote the locations of gas plants, pumping stations or cities with big demand for natural gas. One location can be only one of these there. The numbers on the arrows are the capacities (in appropriate units) of the pipeline that carry gas in the direction of the arrow. Currently the demand supply situation is such that the capacity utilization of the pipelines is very close to 100 percent.

What is the maximum quantity of natural gas that can be transported that can be transported from M to Q?

In a school when a survey is conducted on liking of subjects out of three subjects physics, chemistry mathematics then outcome is as follow.

Total number of students who like physics, chemistry and mathematics is 30, 40, 50 respectively. 10 students shown interest in all three subjects, Number of students who like physics and mathematics both is equal to number of students who like chemistry and mathematics both and is equal to 3/4 times number of students who like physics and chemistry both 15 students like only chemistry.

When class teacher saw this survey report he told head master that at least 20% and at max 40% of those who told they like physics are liars about physics liking. Same percentage for chemistry is 40% to 50%.

Further class teacher added that the liars must belong to those who like only 1 subject and if numbers of liars is more then it belongs to those who like 2 subjects and probability that the who likes all three subjects is a liar is negligible.

According to survey what is the ratio of number of students who like only Physics to those who like only Chemistry to those who like only Maths.

Eight girls – ATHENA, BRISEIS, CALANDRA, DEMETER, ELLIE, FEO, GAIA, and HELEN are sitting in a row facing North. We know the following information about them.

I. The number of girls to the left of ATHENA is equal to the number of girls to the right of GAIA.

II. CALANDRA is sitting three places away to the left of ELLIE.

III. The number of girls sitting between FEO and DEMETER is two.

IV. If BRISEIS and HELEN interchange their positions, then HELEN is fifth to the right of BRISEIS.

V.  CALANDRA is sitting at the extreme left end of the row.

VI. GAIA is sitting exactly between BRISEIS and DEMETER.

Who is sitting extreme right end of row?
