Verbs and Tenses: An Introduction

In the next few weeks, we will be looking at tenses. When we talk about the tenses, we cannot look at them in isolation. We are actually looking at verbs.

In this post we will review the basics of verbs. It is through them that we will tell the tense in which a sentence is.

What are verbs?

Verbs are actions in sentences.  A verb denotes the action or state of being of the subject in a sentence. The actions can be physical or mental.

Work problems involves two or more persons or machines doing a particular task. In this type of problems, the rates of the persons or machines are usually given and the amount of time needed to complete a task is usually asked. Below are the posts that discuss in details these types of problems.

How to Solve Work Problems Part 1 discusses the details of the basic concepts like how the equations are formed and why the equations are equated to 1.

How to Solve Work Problems Part 2 discusses basic examples of work problems. It discusses how two hoses can fill a pool when they are opened simultaneously. It also discusses how a person can do a task alone given the rate of two persons working together.

How to Solve Work Problem Part 2

This is the second part of the Solving Work Problems Series. In the previous post, we have discussed in detail the concept behind how to solve work problems.  In this post, we are going to learn more examples and solve more complicated problems.

Problem 2

A hose can fill a pool in 3 hours, while a smaller hose can fill it in 5 hours. If the hoses are opened together the same time, how many hours will they be able to fill the pool?

Solution

House A can fill the pool in 3 hours, so it can fill 1/3 of the pool in 1 hour.

House A can fill the pool in 5 hours, so it can fill 1/5 of the pool in 1 hour.

Together, they can fill 1/3 + 1/5 of the pool in 1 hour.  » Read more

How to Solve Work Problems Part 1

This is the first part of the Solving Working Problems Series. In this post, we are going to discuss in details the basics of work problems.

Work problems usually involve the time for two or more persons or machines to complete the same job given the rate that they can work. For discussion purposes, let us have the following example.

Work problem:

Ariel can paint a house in 5 days and Ben can do the same job in 6 days. In how many days can they complete the job if they work together?

Discussion and Scratch Work

If Ariel can finish the job in 5 days, then if he were to work one day, he would have completed 1/5 of the job. If he works for two days, then he would have completed 2/5 of the job. Similarly, if Ben can finish the same job in 6 days, if he were to work for one day, then he would have completed 1/6 of the job. If he works for 2 days, he would have completed 2/6 of the job (or 1/3 of the job if reduced to lowest terms).  » Read more

The Civil Service Vocabulary series is a series of vocabulary review for the Civil Service Examination. In this series, I have collected words that usually come out in examinations, wrote their meanings and created sample sentences about them in order for you to remember them easily. Most of the definitions were taken from online dictionaries, although I have simplified many of them for easier reading.

Remember: Being good in vocabulary does not just come overnight (read 5 Ways to Improve Your Vocabulary). It is an accumulation of the words what you have read over time.  » Read more
