Tips to prepare for Quantitative Aptitude Test

Start from the basics: There is no set syllabus that you can strictly follow, in general. But if a particular test appraises you of the topics included, then stick to that. Otherwise go back to the basics of Mathematics, however easy you may think it to be. Follow your academic syllabus so that you can cover all major topics.

Concentrate on fundamentals: The basic concepts of the topics involved should be absolutely clear. Take guidance from your teacher if you get stuck on a particular topic. Do not leave any topic, even if it seems relatively unimportant, as questions can be asked from anywhere. Revise the concepts as and when possible.

Practice: Various entrance exams conduct Quantitative Aptitude as one of the papers. Solve previous year's papers and also model papers of these exams. This will help acquaint with pattern and structure of questions set. The key mantra to success is extensive practice and speed. Calculations of some of the problems can be quite lengthy and time is a major factor during the exams. Practice a lot to acquire speed. Look in the silly mistakes committed earlier and try to improve them.

Take a systematic approach: First solve the practice questions topic wise and later attempt an entire paper. In the beginning you can solve the problems using conventional methods. Later, try out your own shortcut methods to increase speed. But be alert not to jump crucial steps which might confuse you later.

Memorise important formulas, theorems and tables : Quantitative Aptitude includes a lot of formulas, theorems, tables, etc. Write down the important ones that you need to memorise on a sheet of paper. Keep it handy so that you can glance at it any time. Practice a lot to get familiar with them. Practice common square root and cube root problems to quickly solve during exam.

Mark strong and weak sections : While solving different problems, try to find out the topics that you are strong in and also the ones you in which you aren't. Do not neglect the ones you are considerably weaker in, as these might constitute a major part of the paper. Take guidance from your teacher, mentor or senior. You can also take up a coaching class on Mathematics.

Part marking : Many tests on Quantitative Aptitude have part marking scheme. So even if you know that the final answer is wrong, do not cancel the whole problem as you can get part marking for the correct portion.

Know different types of questions : The questions can be deliberately set in a confusing manner or in a more twisted form instead of a more direct form that you are more familiar with. Only practice of different model and earlier years' papers will give you idea of the different ways the questions can be set.

Read the questions carefully : Read the questions carefully so that you understand it properly before answering. A slight misinterpretation of the question otherwise known to you can mar your effort.

Glance before solving : Give a quick glance to the exam paper. First take up the questions you are more comfortable as this will give you the much needed confidence and positive energy to move on with the rest of the paper. Later solve the other questions that you feel are slightly tougher.

Time is essential : Do not waste time if you get stuck in solving a particular question. You might be giving away precious time. Move on to solve the other questions and later if time permits try the ones you have left earlier.

Negative marking : Many tests follow negative marking, so it is advisable not to attempt too many questions on guesswork. In case if you have to then apply the process of elimination (POE) to eliminate the more probable incorrect choices to zero-in on the correct one.

### SOME QUICK MATHS FORMULAS -

2810   14-May-2017, Sun

1. Sum of first n natural numbers = n(n+1)/2
2. Sum of the squares of first n natural numbers = n(n+1)(2n+1)/6
3. Sum of the cubes of first n natural numbers = [n(n+1)/2]^2
4. Sum of first n natural odd numbers = n^2
5. Average = (Sum of items)/Number of items

Arithmetic Progression (A.P.) -
An A.P. is of the form a, a+d, a+2d, a+3d, … where a is called the ‘first term’ and d is called the ‘common difference’
1. nth term of an A.P. tn = a + (n-1)d
2. Sum of the first n terms of an A.P. Sn = n/2[2a+(n-1)d] or Sn = n/2(first term + last term)

Geometrical Progression (G.P.) -
A G.P. is of the form a, ar, ar2, ar3, …
where a is called the ‘first term’ and r is called the ‘common ratio’.
1. nth term of a G.P. tn = arn-1
2. Sum of the first n terms in a G.P. Sn = a|1-rn|/|1-r|

Permutations and Combinations -
nPr = n!/(n-r)!
nPn = n!
nP1 = n
nCr = n!/(r! (n-r)!)
nC1 = n
nC0 = 1 = nCn
nCr = nCn-r
nCr = nPr/r!
Number of diagonals in a geometric figure of n sides = nC2-n

Tests of Divisibility -

• A number is divisible by 2 if it is an even number.
• A number is divisible by 3 if the sum of the digits is divisible by 3.
• A number is divisible by 4 if the number formed by the last two digits is divisible by 4.
• A number is divisible by 5 if the units digit is either 5 or 0.
• A number is divisible by 6 if the number is divisible by both 2 and 3.
• A number is divisible by 8 if the number formed by the last three digits is divisible by 8.
• A number is divisible by 9 if the sum of the digits is divisible by 9.
• A number is divisible by 10 if the units digit is 0.
• A number is divisible by 11 if the difference of the sum of its digits at odd places and the sum of its digits at even places, is divisible by 11.

H.C.F and L.C.M -

• H.C.F stands for Highest Common Factor. The other names for H.C.F are Greatest Common Divisor (G.C.D) and Greatest Common Measure (G.C.M).
• The H.C.F. of two or more numbers is the greatest number that divides each one of them exactly.
• The least number which is exactly divisible by each one of the given numbers is called their L.C.M.
• Two numbers are said to be co-prime if their H.C.F. is 1.
• H.C.F. of fractions = H.C.F. of numerators/L.C.M of denominators
• L.C.M. of fractions = G.C.D. of numerators/H.C.F of denominators
• Product of two numbers = Product of their H.C.F. and L.C.M.

PERCENTAGES -

• If A is R% more than B, then B is less than A by R / (100+R) * 100
• If A is R% less than B, then B is more than A by R / (100-R) * 100
• If the price of a commodity increases by R%, then reduction in consumption, not to increase the expenditure is : R/(100+R)*100
• If the price of a commodity decreases by R%, then the increase in consumption, not to decrease the expenditure is : R/(100-R)*100

PROFIT & LOSS -

• Gain = Selling Price(S.P.) – Cost Price(C.P)
• Loss = C.P. – S.P.
• Gain % = Gain * 100 / C.P.
• Loss % = Loss * 100 / C.P.
• S.P. = (100+Gain%)/100*C.P.
• S.P. = (100-Loss%)/100*C.P.
• If CP(x), Gain(y), Gain%(z). Then y = x*z/100. [Same in case of Loss]

RATIO & PROPORTIONS -

• The ratio a : b represents a fraction a/b. a is called antecedent and b is called consequent.
• The equality of two different ratios is called proportion.
• If a : b = c : d then a, b, c, d are in proportion. This is represented by a : b :: c : d.
• In a : b = c : d, then we have a* d = b * c.
• If a/b = c/d then ( a + b ) / ( a – b ) = ( c + d ) / ( c – d ).

TIME & WORK -

• If A can do a piece of work in n days, then A’s 1 day’s work = 1/n
• If A and B work together for n days, then (A+B)’s 1 days’s work = 1/n
• If A is twice as good workman as B, then ratio of work done by A and B = 2:1

PIPES & CISTERNS -

• If a pipe can fill a tank in x hours, then part of tank filled in one hour = 1/x
• If a pipe can empty a full tank in y hours, then part emptied in one hour = 1/y
• If a pipe can fill a tank in x hours, and another pipe can empty the full tank in y hours, then on opening both the pipes,
• The net part filled in 1 hour = (1/x-1/y) if y>x
• The net part emptied in 1 hour = (1/y-1/x) if x>y

TIME & DISTANCE -

• Distance = Speed * Time
• 1 km/hr = 5/18 m/sec
• 1 m/sec = 18/5 km/hr
• Suppose a man covers a certain distance at x kmph and an equal distance at y kmph. Then, the average speed during the whole journey is 2xy/(x+y) kmph.

PROBLEMS ON TRAINS -

• Time taken by a train x metres long in passing a signal post or a pole or a standing man is equal to the time taken by the train to cover x metres.
• Time taken by a train x metres long in passing a stationary object of length y metres is equal to the time taken by the train to cover x+y metres.
• Suppose two trains are moving in the same direction at u kmph and v kmph such that u>v, then their relative speed = u-v kmph.
• If two trains of length x km and y km are moving in the same direction at u kmph and v kmph, where u>v, then time taken by the faster train to cross the slower train = (x+y)/(u-v) hours.
• Suppose two trains are moving in opposite directions at u kmph and v kmph. Then, their relative speed = (u+v) kmph.
• If two trains of length x km and y km are moving in the opposite directions at u kmph and v kmph, then time taken by the trains to cross each other = (x+y)/(u+v)hours.
• If two trains start at the same time from two points A and B towards each other and after crossing they take a and b hours in reaching B and A respectively, then A’s speed : B’s speed = (√b : √a)

SIMPLE & COMPOUND INTERESTS -
Let P be the principal, R be the interest rate percent per annum, and N be the time period.

• Simple Interest = (P*N*R)/100
• Compound Interest = P(1 + R/100)^N – P
• Amount = Principal + Interest
• when rate of interest time n principal are constant den principal=(C.I.-S.I.)*(100/R)^N

LOGARITHMS -
If a^m = x , then m = loga(x).
Properties :

• logx(x) = 1
• logx(1) = 0
• loga(x*y) = loga(x) + loga(y)
• loga(x/y) = log ax – log ay
• loga(x) = 1/logx(a)
• loga(x^p) = p(loga(x))
• loga(x) = logb(x)/logb(a)

Note : Logarithms for base 1 does not exist.

AREA & PERIMETER -

Volume = 1/3(∏r2h) cu units
Curved Surface Area = ∏rl sq units
Total Surface Area = ∏rl + ∏r2 sq units

• Sphere :

Let r be the radius of the sphere. Then,
Volume = (4/3)∏r3 cu units
Surface Area = 4∏r2 sq units

• Hemi-sphere :

Let r be the radius of the hemi-sphere. Then,
Volume = (2/3)∏r3 cu units
Curved Surface Area = 2∏r2 sq units
Total Surface Area = 3∏r2 sq units

• Prism :

Volume = (Area of base)(Height)
