First calculate the arithmetic mean of readings, Xmean = X1 + X2 + X3 + X4 + X5 =(2.63+2.56+2.42+2.71+2.80)/5 = 2.62s The absolute error can be calculated as, For first reading, ΔX1=(2.63−2.62) ΔX1=0.01s For second reading, ΔX2=(2.56−2.62) ΔX2=0.06s For third reading, ΔX3=(2.42−2.62) ΔX3=0.20s For forth reading, ΔX4=(2.71−2.62) ΔX4=0.09s For fifth reading, ΔX5=(2.80−2.62) ΔX5=0.18s Calculate the arithmetic mean of absolute errors, ΔXmean=(ΔX1+ΔX2+ΔX3+ΔX4+ΔX5)/5 ΔXmean=(0.01+0.06+0.20+0.09+0.18)/5 ΔXmean=0.54/5 ΔXmean=0.11s Calculate the relative error, RE=ΔXmean/Xmean RE=0.11/2.62 RE=0.04s Calculate the percentage error, PE=(ΔXmean/Xmean)×100 PE=(0.11/2.62)×100 PE=4%

‘The Portrait of a Lady’ is a descriptive story describing Khushwant Singh’s grandmother. He describes his relationship with his grandmother in the story – The Portrait of Lady. He recalls his grandmother as a short, old, slightly bent lady. He sketches the lady as not very pretty but constantly beautiful throughout her life and the twenty years that the author had stayed with her. She was healthy and lived a very long life. In the story, the author describes the 3 phases of relationship in the story which include the time of complete dependence, the sharing of room, and losing the common link of friendship by getting his privacy. Grandmother had an orthodox kinda mentality and disapproved of Music lessons taught to the author in the school. Animal lover, theist, and the formerly caring lady died out of very usual mild fever. She spent her last chapter chanting the god’s name and praying. She ignored the protest done by the author and the author’s parents. Finally, with a peaceful pallor spread on her face, she died. During the customary ceremony, before the funeral, the corpse was lying in her room where 1000’s sparrows sat scattered on the floor, very quiet. They showed their sorrow by taking no notice of the bread crumbs kept by the author’s mother and flew away once the body was carried away and came back never again.

Imagine :- If you have two commodities noodles and spaghetti. If you want to produce spaghetti you will have sacrifice some proportions of resources used to produce noodles or if you have to make noodles you will have to sacrifice some of the resources used to make spaghetti. It means that MOC works on a principle that to gain one additional unit of a commodity an economy needs to sacrifice some number of units of another commodity
