Dear friend
Practice makes everything easy. A person become able or capable only after practising. I suggest you to practise your self in that subject in which you want to become highly talented. You know that there is a well known proverb that practice makes the man perfect. I suggest you some books of mathematics please solve them with the help of a tutor if you intends to improve your aptitude solving skill.

hi dear to improve your aptitude skills go for RS Agrawal book practice as much as you can do and to solve the question qrickly learn basic and short trick methods given in that book and also to solve mathematical portion quickly adopt some basic method of vaidik mathematics.

all the best

Hi,

You need to practice or play solving puzzles, sudoku, chess to keep your mind sharp and alert.
You can study the RS Aggarwal's books for english, aptitude for mastery in the these fields. You need to practice previous papers to speed up your solving time. Manage time and prepare daily time table for the task to be completed and at night analyse what is done and what left and why. Where you lack you will get it soon.

hai all the members thank u thank u v much . i will try my level best

Dear friend,

The only way to develpoe the aptitude skills is doing more number of problems as many as you can and as many number of times as possible.

Why because if you do the tough problem or any kind of problem for a few number of times, obviously after the completion of 6times or 7 times of doing the same problem, the next time you may not need to go for written calculation because it is already will store in your mind and sometimes it may lessen your problem by not going for number of steps.

You can solve in very few steps.

So i suggest you to repeat repeat repeat.............

Hi friend

you can crack the Aptitude exam easily, if you work out daily 10 to 20 sums

here i will send the different topic with formula,so that it is easy to learn

True discount
formula


IMPORTANT CONCEPTS

Suppose a man has to pay Rs. 156 after 4 years and the rate of interest is 14% per annum. Clearly, Rs. 100 at 14% will amount to R. 156 in 4 years. So, the payment of Rs. now will clear off the debt of Rs. 156 due 4 years hence. We say that:

Sum due = Rs. 156 due 4 years hence;

Present Worth (P.W.) = Rs. 100;

True Discount (T.D.) = Rs. (156 - 100) = Rs. 56 = (Sum due) - (P.W.)

We define: T.D. = Interest on P.W.; Amount = (P.W.) + (T.D.)

Interest is reckoned on P.W. and true discount is reckoned on the amount.

IMPORTANT FORMULAE

Let rate = R% per annum and Time = T years. Then,

1. P.W. = 100 x Amount = 100 x T.D.
100 + (R x T) R x T
2. T.D. = (P.W.) x R x T = Amount x R x T
100 100 + (R x T)
3. Sum = (S.I.) x (T.D.)
(S.I.) - (T.D.)
4. (S.I.) - (T.D.) = S.I. on T.D.

5. When the sum is put at compound interest, then P.W. = Amount
1 + R T
100

Races and Games


Races: A contest of speed in running, riding, driving, sailing or rowing is called a race.

Race Course: The ground or path on which contests are made is called a race course.

Starting Point: The point from which a race begins is known as a starting point.

Winning Point or Goal: The point set to bound a race is called a winning point or a goal.

Winner: The person who first reaches the winning point is called a winner.

Dead Heat Race: If all the persons contesting a race reach the goal exactly at the same time, the race is said to be dead heat race.

Start: Suppose A and B are two contestants in a race. If before the start of the race, A is at the starting point and B is ahead of A by 12 metres, then we say that 'A gives B, a start of 12 metres'.

To cover a race of 100 metres in this case, A will have to cover 100 metres while B will have to cover only (100 - 12) = 88 metres.

In a 100 race, 'A can give B 12 m' or 'A can give B a start of 12 m' or 'A beats B by 12 m' means that while A runs 100 m, B runs (100 - 12) = 88 m.

Games: 'A game of 100, means that the person among the contestants who scores 100 points first is the winner'.

If A scores 100 points while B scores only 80 points, then we say that 'A can give B 20 points'.

Boats and steams


Formula


Downstream/Upstream:

In water, the direction along the stream is called downstream. And, the direction against the stream is called upstream.

If the speed of a boat in still water is u km/hr and the speed of the stream is v km/hr, then:

Speed downstream = (u + v) km/hr.

Speed upstream = (u - v) km/hr.

If the speed downstream is a km/hr and the speed upstream is b km/hr, then:

Speed in still water = 1 (a + b) km/hr.

Rate of stream = 1 (a - b) km/hr.

Ratio and Proportion

Formula


Ratio:

The ratio of two quantities a and b in the same units, is the fraction and we write it as a : b.

In the ratio a : b, we call a as the first term or antecedent and b, the second term or consequent.

Eg. The ratio 5 : 9 represents 5 with antecedent = 5, consequent = 9.
9

Rule: The multiplication or division of each term of a ratio by the same non-zero number does not affect the ratio.

Eg. 4 : 5 = 8 : 10 = 12 : 15. Also, 4 : 6 = 2 : 3.

Proportion:

The equality of two ratios is called proportion.

If a : b = c : d, we write a : b :: c : d and we say that a, b, c, d are in proportion.

Here a and d are called extremes, while b and c are called mean terms.

Product of means = Product of extremes.

Thus, a : b :: c : d (b x c) = (a x d).

Fourth Proportional:

If a : b = c : d, then d is called the fourth proportional to a, b, c.

Third Proportional:

a : b = c : d, then c is called the third proportion to a and b.

Mean Proportional:

Mean proportional between a and b is ab.

Comparison of Ratios:

We say that (a : b) > (c : d) a > c .
b d
Compounded Ratio:

The compounded ratio of the ratios: (a : b), (c : d), (e : f) is (ace : bdf).

Duplicate Ratios:

Duplicate ratio of (a : b) is (a2 : b2).

Sub-duplicate ratio of (a : b) is (a : b).

Triplicate ratio of (a : b) is (a3 : b3).

Sub-triplicate ratio of (a : b) is (a1/3 : b1/3).

If a = c , then a + b = c + d . [componendo and dividendo]
b d a - b c - d
Variations:

We say that x is directly proportional to y, if x = ky for some constant k and we write, x y.

We say that x is inversely proportional to y, if xy = k for some constant k and
we write, x 1 .
y

Simplification

Formula

: Home > Aptitude > Simplification > Important Formulas
'BODMAS' Rule:

This rule depicts the correct sequence in which the operations are to be executed, so as to find out the value of given expression.

Here B - Bracket,
O - of,
D - Division,
M - Multiplication,
A - Addition and
S - Subtraction

Thus, in simplifying an expression, first of all the brackets must be removed, strictly in the order (), {} and ||.

After removing the brackets, we must use the following operations strictly in the order:

(i) of (ii) Division (iii) Multiplication (iv) Addition (v) Subtraction.

Modulus of a Real Number:

Modulus of a real number a is defined as

|a| = a, if a > 0
-a, if a < 0
Thus, |5| = 5 and |-5| = -(-5) = 5.

Virnaculum (or Bar):

When an expression contains Virnaculum, before applying the 'BODMAS' rule, we simplify the expression under the Virnaculum.

Problems on Numbers

Some Basic Formulae:

(a + b)(a - b) = (a2 - b2)

(a + b)2 = (a2 + b2 + 2ab)

(a - b)2 = (a2 + b2 - 2ab)

(a + b + c)2 = a2 + b2 + c2 + 2(ab + bc + ca)

(a3 + b3) = (a + b)(a2 - ab + b2)

(a3 - b3) = (a - b)(a2 + ab + b2)

(a3 + b3 + c3 - 3abc) = (a + b + c)(a2 + b2 + c2 - ab - bc - ac)

When a + b + c = 0, then a3 + b3 + c3 = 3abc.

As to develop the above said skills you need to practice extensively using reference books and previous years question papers. You can also access external help from friends and also coaching centers. These external resources will help in those areas which one need special attention. Practice is the best solution to improve exam skills.

First just try to speak out in English with your friends instead of Hindi or any other local language.You need not feel shy by speaking in English but think that your developing ourselves and your own skills.

You can refer books of GRE Barron and R.S Agarwal to develop your aptitude skills but whats the use of trying to learning aptitude skills without knowing English properly.

If you feel difficulty in developing these skills then its better that you go for coaching centers.

all the best

See, Aptitude skill development is a long term process. AS you are in 3rd year, it is a high time for you to start this.

You need to solve various books on Aptitude, I will suggest following books:-

-Aptitude by R.S.Aggarwal

-Berron's

-Verbal and non verbal by R.S.Aggarwal

-Logical reasoning by R.s.Aggarwal


All the tips and tricks are given in these books.

More you practice , more you will gain. This is the only success formula for this.

Please post your queries here.

Best of luck

regards.
