Delhi Police Constable Mock Test - 3 - Question 25

Which of the following are excluded from the National Income to calculate Personal Income?

  1. Corporate Tax

  2. Personal Tax payments

  3. Transfer payments to the households from the Government

  4. Undistributed profits

Select the correct answer using the code given below.

Detailed Solution for Delhi Police Constable Mock Test - 3 - Question 25
  • We can subdivide the National Income into smaller categories. The part of NI which is received by households is called Personal Income (PI). It is calculated as follows.

  • First, out of NI, which is earned by the firms and government enterprises, a part of the profit is not distributed among the factors of production. This is called Undistributed Profits (UP). We have to deduct UP from NI to arrive at PI since UP does not accrue to the households.

  • Similarly, Corporate Tax, which is imposed on the earnings made by the firms, will also have to be deducted from the NI, since it does not accrue to the households.

  • On the other hand, the households do receive interest payments from private firms or the government on past loans advanced by them. And households may have to pay interests to the firms and the government as well, in case they had borrowed money from either. So we have to deduct the net interests paid by the households to the firms and government.

  • The households receive transfer payments from the government and firms (pensions, scholarships, prizes, for example) which have to be added to calculate the Personal Income of the households.

  • Thus, Personal Income (PI) ≡ NI – Undistributed profits – Net interest payments made by households – Corporate tax + Transfer payments to the households from the government and firms.

  • However, even PI is not the income over which the households have complete say as they have to pay taxes from PI. If we deduct the Personal Tax Payments (income tax, for example) and Non-tax Payments (such as fines) from PI, we obtain what is known as the Personal Disposable Income. So Personal Income includes tax payments.

Hence option (a) is the correct answer.

Delhi Police Constable Mock Test - 3 - Question 87

Two rabbits start simultaneously from two rabbit holes towards each other. The first rabbit covers 8% of the distance between the two rabbit holes in 3 hours, The second rabbit covered 7 / 120 of the distance in 2 hours 30 minutes. Find the speed (feet / h) of the second rabbit if the first rabbit travelled 800 feet to the meeting points.

Detailed Solution for Delhi Police Constable Mock Test - 3 - Question 87

Since the second rabbit covers 7/120 of the distance in 2 hours 30 minutes
⇒ it covers 8.4 / 120 = 7% of the distance in 3 hours.

Thus, in 3 hours both rabbits together cover 15% of the distance which means 5% per hour so they will meet in 20 hours.

The ratio of speeds = 8 : 7.
⇒ the second rabbit would cover 700 ft to the meeting point in 20 hours and its speed would be 35 feet/hr.

So Option is correct

Delhi Police Constable Mock Test - 3 - Question 89

Refer to the data below and answer the questions that follow.

Anoop and Sandeep can dig a well each in 10 and 5 days respectively. But on a particularly difficult terrain the work is such that due to fatigue every' subsequent day the efficiency of a worker falls by 10%.
Q.If Anoop is given a task of digging one such well in the difficult terrain, then in how many days will he finish the work?

Detailed Solution for Delhi Police Constable Mock Test - 3 - Question 89

Correct Answer :- d
