Q1. A hypothetical economy produces only two commodities X and Y. Thevestwo commodities serve as intermediate inputs in each others production. Toproduce a unit of X, 0.2 unit of X and 0.6 unit of Y are needed. To produceaunit of Y, 0.4 unit of X and 0.3 unit of Y are needed. Three and five labour-hours are required to produce a unit of X and a unit of Y respectively. Thewage rate is 20 per labour-hour. If the final demand of X increases by 150units and that of Y decreases by 120 units, find:(1) change in the gross outputs of each of the two commodities;(i1) change in labour requirement;(2010)(iii) change in the value-added in the two producing sectors solution of matrices of maths

Answer:
An owl is a bird. There are two basic types of owls: typical owls and bam owls. Owls live in almost every country of the world. Owls are mostly nocturnal, meaning they are awake at night. Owls are predators—they hunt the food that they eat. Owls hunt for mice and other small mammals, insects and even fish. Owls are well adapted for hunting. Their soft, fluffy feathers make their flight nearly silent. They have very good hearing which helps them to hunt well in the darkness. The sharp hooked beaks and claws of the owl makes it very easy to tear apart their prey quickly, although owls also eat some prey whole.Owl’s eyes are unusual. Like most predators, both the eyes of the owl face front. The owl cannot move its eyes. Owls are far—sighted, which means they can see very well far away………. but they can’t see dose very well at all. Fortunately, their distant vision is what they use for hunting and they can see far away even in low light. Owls have facial disks around their eyes, tufts of feathers in a circle around each eye. These facial disks are thought to help the Owl’s hearing. Owls can turn their heads 180 degrees. This makes it look like they might be able to turn their heads all the way around, but 180 degrees is all the owl needs to see what’s going on all around its. Perhaps because of the Owl’s mysterious appearance, especially its round eyes and flexible neck, there are a lot of myths and superstitions about owls. Many cultures believe that owls are unusually wise. Because owls are nocturnal, some cultures associate owls with bad omens. The screech of the bam owl is considered by many to sound eerily human, like a person screaming. However, owls probably do not interact with the fates of humans at all. In fact, some owl species may become extinct because of humans.
Which of the following is true?
(a) The facial disks of the owl help them to see.
(b) Owls have a strong, bent beak.
(c) Most owls hunt for food during the day.
(d) Owls are dangerous to humans
