Important Points to note:
1. Try to find Main Point of the paragraph. As the sentences when constructed to make a paragraph presents an idea. Try to find that idea and see what role a particular sentence will play to depict the whole picture. Then arrange them accordingly to make paragraph coherent.

2. Try to see verbal connectives and logical connectives as they give hints regarding constructing the paragraph logically.
3. Try to see analogies as they should proceed with real life examples.

Internet is for nerds => Internet is for all nerds. Shyam is a nerd. So, internet is for Shyam is a valid conclusion.
Similarly, Capital punishment is for killers => Capital punishment is for all killers. Ravan is a killer. So, Capital punishment is for Ravan is a valid conclusion.
In 2, 'people' is mentioned in the conclusion but not in any of the statements. So, 2 is wrong.
In 4, the conclusion need not necessarily true.
So, 1 and 3 is the correct answer.

Hi Esakiraj,

Implementing the following strategy can help you increase your accuracy in Reading Comprehension:

1. Identify the theme of every paragraph while reading the RC for the first time.

2. Identify the specific questions. These are questions that pertain to a specific paragraph in the essay. These questions can be answered with greater accuracy.

3. For the 'generic questions', try to eliminate the least likely options. As a general strategy, choose the RC whose topic is familiar to you.

Try to answer at least three of the four questions in the RC. You can practise RC questions at the following links:

f(1) = a+b+c+d = 0
f(-1) = -a + b -c +d = 0
Adding, we get, b+d = 0
f(0) = d = 2 => b = -2

The speed of the train in m/s is 108*5/18 = 30 m/s
As it took the train 12 seconds to cross the platform, the total distance covered is 12*30 = 360 m/s
The length of the train is 280 m, hence the length of the platform is 100 m

If a man crosses the platform in 10 seconds, his speed is 100/10 = 10 m/s

8m/s

Hi Swaroop,

The NMAT cut-off last year was 207. A safe score for a call would be around 213. If you can tell us more about which areas you are facing difficulty with, we will be able to pin-point specific things that you have to work on to improve your score and clear the cut-off. In any case, speed is an important factor in NMAT. Try to work on your speed. This will increase your number of attempts. Also, analyse the mocks to check where you are going wrong. If you find that you are weak in certain areas, work on those areas to answer questions in the next mock. Do let us know your weak areas so that we will be able to guide you better.

i score 45 in english weak in vocab barely score 2-3 answers correct out of 10 and grammar i leave rcs in nmat because it take too much time and unable to solve implicit questions in logical reasoning part, i have no idea about these questions..in quant sometimes i score 90+ , 70-75 and sometimes 50 based on difficulty level..

After the tank is tilted, the volume of empty space in the tank equals 1/2*60*60*40 = 72 litres.
This includes 32 litres of water which was collected.
So, the volume of the empty space before was 40 litres.
Hence, the height of the empty space was 40*1000/(40*60) = 16.66 cm
Hence, the height of water originally was 80-16.66 = 63.33 cm

Answer is c

@Maruti Sir, how u got 1/2*60*60*40? Can you please explain.

Hi Chandan,

Questions in ratio, proportion and percentages are quite commonly asked in competitive examinations. The single most important trick in solving these kind of questions is to ensure that you get the denominator correct while solving it.

For example, the percentage of profit will differ based on whether it is calculated on cost price or on selling price. It is important for a student to keep in mind these kind of differences to ensure that silly mistakes are not committed while solving questions.

The other important concept in ratio and proportion is the rule of Alligation.

Whenever a problem on profit loss is given, identify the data regarding cost price, selling price, marked price, discount and profit/loss quickly. If the data of any of the above terms is not given, then try to find its value using the information of the other terms. Have these 4 formulae on your tips and practice a lot:
1) Profit/Loss = Selling Price - Cost Price
2) Profit/Loss % = $$\frac{Profit/Loss}{Cost Price} * 100$$
3) Marked Price - Discount = Selling Price
4) Selling Price = Marked Price ($$1-\frac{Discount}{100}$$)

Hi like vikas said our DI CHEAT SHEET or FORMULA SHEET will help you in that
