Seven friends, namely Piyashi, Qualin, Ravanya, Sanya, Tanya, Urvashi and Varsha passed their Xth board examination in 2007. The result was announced on a Sunday and from the next day, they started organising dinner parties on consecutive days. Each one of them organised exactly one party. On none of the days was more than one party organised. They decided that only four kinds of items viz. Dosa, Pizza, Burger and Idli would be ordered for the dinner parties. The costs per plate of Dosa, Pizza, Burger and Idli were Rs. 25, Rs. 45, Rs. 20 and Rs.15 respectively. The following additional information was available: I. In each of the dinner parties, total number of plates ordered, taking all four items together was either 8 or 9. II. Each dinner party had different combination of number of plates of different items and each type of item was ordered for at least one plate but not more than three plates. III. Qualin hosted the party immediately after Urvashi. IV. Piyashi, Ravanya, Sanya and Varsha had ordered for more number of plates than the other three and hosted their parties immediately one after the other in that order only. V. The total number of plates of Dosa, Pizza, Burger and Idli ordered were 14, 16, 18 and 12 respectively including all dinner parties. VI. In each dinner party, at least three items were ordered for 2 or more plates. If the maximum possible amount for a dinner party was paid on Monday, then who hosted that party?
A woman from New Orleans who read the article on ravens that I wrote when I had just started to investigate whether and how ravens share, wrote me: "I did not have so much trouble as you did in showing that ravens share. I see them at my feeder - they even feed one another". There are no ravens in New Orleans, nor anywhere else in Louisiana. Perhaps what she actually saw were several large dark birds (crows? Grackles?), one of which fed another one or two (probably their grown offspring traveling along with them). People commonly confuse personal interpretations with factual observations. This tendency is a special bane in getting reliable observations on ravens because so much ingrained folklore about them exists that it is difficult to look at them objectively. I once read an article about a trapper/writer in Alaska. Knowing he would be familiar with ravens in the north, I wrote to ask him if he had seen ravens feeding in crowds. He had a lot of raven stories to tell. First, he said "everyone" he knew, knew that ravens share their food. He was surprised at the ignorance of us armchair scientists so far away, who would even question it. Ravens were "clever enough" to raid the fish he kept on racks for his dogs. They proved their cleverness by posting a "twenty-four-hour guard" at his cabin. (How did he distinguish this, I wondered, from birds waiting for an opportunity to feed?) As soon as he left the cabin, a raven was there to "spread the word". (Read: Flew away and/or called.) He claimed that one raven "followed" him all day. (Read: He occasionally saw a raven.) It then "reported back" to the others so that they could all leave just before he got back from his day on the trapline. (Read: He saw several leave together, and there were none when he got back to the cabin door.) Many of the birds "raided" (fed from?) his fish rack, and his idea of their "getting out the word" to ravens for miles around is that the one who discovers the food calls, and thereby summons all the birds in neighboring territories, who then also call in an ever-enlarging ring of information sharing. (An interesting thought).) It was no mystery to him why the birds would do this: they are "gossiping". "It seems obvious", he said, "that the birds get excited, and they simply cannot hold in their excitement - that lets others know". Any why should they evolve such transparent excitement? That, too, was "obvious": "Because it is best for the species". This stock answer explains nothing. It was disturbing to me to see anyone so facilely blur the distinction between the observations and interpretations and then even go so far as to make numerous deductions without the slightest shred of evidence. When I was very young and did not "see" what seemed obvious to adults, I often though I was stupid and unsuited for science. Now I sometimes wonder if that is why I make progress. I see the ability to invent interconnections as no advantage whatsoever where the discovery of truth is the objective. There are those who believe that science consists entirely of disproving alternative hypotheses, as if when you eliminate the alternative views, the one you have left is right. The problem is that there is no way to think of all the possible hypotheses that nature can devise. More than that, you have to prove which is the most reasonable. But any one hypothesis can, with a limited data set, be reasonable. There is at least a touch of truth in the idea that any variable affects another. If you look long and determinedly enough you will find that almost any variable element you choose to examine apparently affects the behavior you are studying. You have to be able to skim over what is not important or relevant to your problem, and to concentrate long enough on the prime movers to unearth sufficient facts that, presuming they are recognized, add up to something.

The RaceMo that was showcased at the 2018 Auto Expo saw the 003 sticker and it is the electric version of the 2-seater sports car. Having showcased the car in India, Tata Motors has also answered those critics who thought that project was shelved. Background : In 2014, when the company was not even thinking about CNG or electric cars, 2018 sees a big change in approach. At the Auto Expo 2018, Tata Motors brought out products which showed the direction the company is taking as far as their product portfolio goes. Tata Motors looks to be like a company on a mission. They are aware of the Indian market being demanding and wanting the best, so they have come up with something that people can't resist. The huge turnout of electric vehicles was expected from the carmaker but there were a few surprises thrown in. The company showcased the RaceMo sports coupe in India for the first time but instead of just bringing in the petrol car which it showcased at the 2017 Geneva Motor Show which was labelled 001. So having a 003 in the Auto Expo as an upgrade was something really wonderful. Key Points : · The Racemo is a 2-seater sports car that sits under 4 metres in length (3835 mm) and sports a rear-mounted mid-engine · The car uses a special body that has Tata's MOFlex multi-material sandwich structure · Tata says this is a 'structural technology that enables greater freedom in surface design, efficient large-scale part integration leading to modularity and faster time to market' · The all-electric version of the Racemo has been christened 'Racemo +-' and it shares its stying with the petrol powered sibling · Designed at the Tata Motors' Design Studio in Turin, Italy, Racemo does draw on Tata's design language that has elements like the 'Humanity Line', and 'Diamond DLO' that we have seen on recent cars from the Tata stable · The Racemo comes with a ground clearance of 165 mm and this is important as far as Indian road conditions are concerned · The all-electric RaceMo comes with a 200 bhp electric motor that pulls power from a lithium battery pack · The RaceMo electric can do 350 km on a single charge and there's also the option of fast charging for the battery pack
