Explain classification of incomes of a non-trading concern with illustrations.

Answer»

There are two types of incomes of a non-trading concern :

1. Revenue incomes and
2. Capital incomes.

1. Revenue income: Incomes received for the regular activities of the concern are known as revenue incomes or receipts. Revenue incomes are those incomes without which the activities of the concern cannot be carried out.

Illustrations: Admission fees of members, Subscriptions, Interest on investments, Incomes from various activities, Locker’s rent, Rent of hall, Government grant or subsidy, Income from entertainment programme, Small amounts of donations or charity, Sale of old newspaper, Sale of sports equipment, Discount, Commission, etc. The revenue incomes or receipts are recorded on the credit side of Income and Expenditure Account. The objective of revenue incomes are to procure regular income.

2. Capital incomes: The incomes which are not received regularly or repeatedly and whose benefit is going to be received by the concern for a longer period, are known as capital incomes or receipts.

Illustrations: Donation, Charity, Subscription received for life membership, Amount of loan taken, etc. Profit arising from the sale of fixed asset is a capital income but it is generally credited to Income-Expenditure Account instead of adding to capital fund. Generally in non-trading concerns except borrowings capital incomes such as donations, legacy, etc. are added in capital fund or are shown separately from capital fund on liabilities side of a Balance Sheet. The objective of capital income is to procure long term fund.

Can you recount any real life experience where things went awry due to last-minute hurry? Write an anecdote in about 150 words.

Answer»

Last Minute Fiasco: 

The phone call came from my friend to tell me that his father died and the cremation would be at 4.00 p.m. in his compound. He asked me to convey the message to our common friend George. George and I live at Irinjalakuda and my friend whose father died lives in Thrissur. By car it would take only 30 minutes to reach my friend’s house to attend the cremation. So George and I decided to leave Irinjalakua at 3 o’clock after buying a wreath from a local flower shop.

We chose an expensive wreath with white roses and lilies. We started driving. Unfortunately, there was an accident on the Karuvannur bridge which we had to cross to reach Thrissur. We were delayed by half an hour. Then we rushed and reached our friend’s home around 4.30 p.m. We saw him standing in front of his house.

He looked quite sad. We left the wreath in the car as we knew the cremation had already taken place. We spent a few minutes with our friend condoling with him. From the obituary column of the local newspaper we saw that somebody had died at Irinjalakuda. We got the address of the bereaved family and went to the house the placed the wreath at the foot of the dead body of the stranger. The relatives of the dead people were surprised to see two strangers placing such an expensive wreath. They would never know it was intended for the dead father of our friend!

Imagine that the farmer in Post Early for Christmas feels guilty over his actions that led to utter chaos in the post office. He goes to the postal assistant’s house to apologise. However the postal assistant refuses to meet him. He leaves a message for her. Write the message for him.

Answer»

Madam, I know you are angry with me for what happened at the post office. I am really sorry. That is why I came to apologize to you. But since you have refused to meet me, I am leaving this note to let you know what actually happened and how sorry I am. 

When I was coming to the post office I read in the newspaper an item like this: “Bomb found in post office. Scotland Yard has issued a warning that a time bomb disguised as a Christmas parcel was discovered in a London Post office. Any suspicious looking parcel should be reported at once to the local police station.” 

I had this at the back of my mind when the tourist came with the parcel. You know he looked suspicious and look at the way he talked about the parcel, asking so many questions about the time it reaches the central post office and so on. And when you said that the parcel was ticking, I naturally thought there was a time bomb inside.

I asked you to bring a bucket of water to prevent it from exploding and killing or maiming all of us. I only thought of our safety and I had no plan to spoil anybody’s anything. But somehow it turned out to be a blunder on my part. I am sorry. I am sure you are gracious enough to forgive me for the mistake I made as it was made with good intentions.

The Postmaster General 

London

Sir, 

Sub: RUINING MY SWISS CLOCK I had bought an expensive Swiss clock and I wanted to send it to my friend as a Christmas present. I handed over the packet to the Assistant at the Milton Square Post office and she accepted it and gave me a receipt. I had forgotten by gloves on the counter and when I went back to collect them, I saw my packet being  opened by a policeman. When I asked him the reason for it, I was told that there was a ticking sound and somebody suspected it to contain a time tomb. So it was immersed in water. My precious gift to my friend was ruined.

I want to lodge my protest against such foolish behaviour on the part of your workers in the post office. You have spoiled the joy of my Christmas. I paid 155 Pounds for the clock and then the postal charges. I want a proper compensation forthe loss your worker has caused.

I hope you will take immediate action.

Yours faithfully, 

Sam Peter.

Oh My God! Yesterday I was dead tired riding kilometres after kilometres delivering the goods to the customers. Sometimes they live in almost inaccessible places, and I have to walk carrying the packet to give them. Well, I should not complain because only because they buy things online I have a job to do. So, God, make more people buy more things online!

Answer»

[email protected]

Hope you are ne. This year I wanted to send you a precious Swiss clock as my Christmas present. I am sure you would be happy with it because it was a beautifully crafted clock. But you know what happened! The Postal Assistant accepted my packet. Then some foolish fellow standing nearby heard the clock ticking and his perverted mind thought the packet had a time bomb. He told people it was ticking and it would explode soon. He asked the Postal Assistant to get a bucket of water and immerse the packet in it to prevent it from exploding! Thus the precious clock got ruined. I’m so sorry, Ranbir!

I have complained to the Post Master General about the ridiculous act.

Hope you had a merry Christmas. Sam Peter

Comment on the role of the farmer in the play.

Answer»

It was actually the farmer who caused all the havoc in the post office. First of all he scared the people by reading out the news loudly: “Bomb found in a post office. Scotland Yard has issued a warning that a time-bomb disguised as a Christmas parcel was discovered in a London post office. Any suspicious-looking parcel should be reported at once to the local police station.” With his ‘expertise’ he is sure that the ticking parcel given by the tourist contains a time bomb. He is the one suggesting to call a policeman. He scares the people by telling them the timebomb will soon go o and they should take cover. He is the one who asks the Assistant to bring a bucket of water. Thus he was instrumental for all the commotion and mischief there.

28337.

Bring out the humour in the play.

Answer»

There are many humorous situations in the play. We laugh when we see somebody coming to the post office and asks where he can get stamps. Another person comes asking for a pint of beer. The deaf man creates a lot of humour as he misunderstands book as cook, said as bed and later Ted. We laugh a lot when see an old lady coming to consult the Assistant about her cat. The greatest humour is when the tourist comes with his ticking parcel and the anxiety created by it. As the parcel with the lime-bomb’ is thrown into water and people run for cover, we really laugh at the foolishness of people.

28338.

What makes the play humorous (Its characters and their traits or the incidents in it).

Answer»

The play is made humorous by the traits of the characters and also the incidents. The deaf old man makes us laugh a lot. He hears the word book as ‘cook’ and ‘said’ as ‘bed and Ted’. He even accuses the Assistant of being deaf! Then we see the Old Lady coming to complain about her cat thinking the post office to be a clinic for injured animals. We have the Farmer who thinks he knows all about time-bombs. We have the dirty urchin – Bertie- with his horrible English.

We have the Foreign Tourist with his terrible accent. Then there is the incident of a man coming to the post office and asking where he could get a stamp! Another fellow wants a pint of beer. The funniest incident is when people run for cover and the parcel is dropped in a bucket of water. The Tourist had brought a beautiful clock from Switzerland as a Christmas present to his friend. And see what havoc it caused and how it ended up in water!

What precaution did Kemp take on reading the letter sent to him by Griffin?

Answer»

The precaution taken by Kemp after reading the letter send to him by Griffin prove that he took the contents of the letter very seriously. He could recognize Griffin’s matter-offact tone and he knew that this angered man meant business. Therefore, he left his meal at once and instantly called his maid-servant to check all the window-fastenings and close all the shutters. He personally closed the shutters of his study-room. Then he equipped himself with his revolver to protect himself against any odds. Next, he wrote a note to Adye, telling him all about the letter. He suggested that he was ready to act as bait for Griffin and requested Adye to make all preparations to capture him. He felt certain that Griffin would walk into this trap and would be captured the moment he would come to assault him. He then asked the maid to carry the note to Adye and gave her strict instructions about the way to be followed to leave the house. He then returned to his lunch, but even while eating he mentally reviewed all the details and felt satisfied with the prompt action taken by him. His excitement and certainty about trapping Griffin established his seriousness regarding the contents of the letter.
