Let’s discuss below important Maths formulas and shortcuts for the AFCAT exam:-

AFCAT Maths Tricks: Decimal Fraction

In a decimal fraction, the denominator is an integer power of ten and it is expressed by using decimal notation, where the denominator is not clearly mentioned.

Examples of Decimal Fraction are:  1/10 = .1, 1/100 = .01

  • How to Convert a Decimal into Common Fraction?

Let’s put 1 in the denominator under the decimal point and after the decimal point put as many zeros as the number of digits and reduce the fraction to its lowest term and remove the decimal point. For examples: 0.5 = 5/10=1/2

AFCAT Maths Tricks: Basic Formulas 

  1. (a + b)(a – b) = (a2 – b2)
  2. (a + b)2 = (a2 + b2 + 2ab)
  3. (a – b)2 = (a2 + b2 – 2ab)
  4. (a + b + c)2 = a2 + b2 + c2 + 2(ab + bc + ca)
  5. (a3 + b3) = (a + b)(a2 – ab + b2)
  6. (a3 – b3) = (a – b)(a2 + ab + b2)
  7. (a3 + b3 + c3 – 3abc) = (a + b + c)(a2 + b2 + c2 – ab – bc – ac)
  8. When a + b + c = 0, then a3 + b3 + c3 = 3abc.

AFCAT Maths Tricks: Simplification

Learn the rule of ‘BODMAS’: The rule of ‘BODMAS’ is an easy way to learn simplification. The full form of the ‘BODMAS’ rule is as follows:-

  • B-Bracket, O-Of, D-Division, M-Multiplication, A-Addition, S-Subtraction

So, when you are simplifying a problem first remove all the brackets and follow the orders like ‘of’, ‘division’, ‘multiplication’, and at last ‘subtraction’ accordingly.

AFCAT Maths Tricks: Average

The average is equal to the total of observations or the number of observations.

Suppose a train runs and covers at a certain distance at x kmph and with an equal distance at y kmph. Then, during the whole journey, the average speed of the train would be  (2xy/x+y) kmph.

AFCAT Maths Tricks: Percentage

  • Percentage means many hundreds. As for example, x% means x hundreds and it should be written as: x%=x/100
  • x/y can be expressed as (x/y x 100)%
  •  The Increase/Decrease of percentage:  When the quantity grows, then we can assume its percent increase. And when the quantity shrinks then its percent decrease.
  • Result on Depreciation: Suppose the present value of a product be M.  If it depreciates at the rate of N% per annum. Then the value of that product after N years = M (1-(N/100) n.

AFCAT Maths Tricks: Ratio

The concept of the ratio can be expressed in the fraction as X: Y. Here, X is the antecedent and Y is the consequent. For example: In the ratio 1:2, 1 is the antecedent and 2 is the consequent.

AFCAT Maths Tricks: Proportion

If two ratios are equal then they are proportional. For example: a: b=c: d. Here, in this example, we can say a, b, c, d are in proportion and a and d are called extremes, while b and c are called mean terms.

AFCAT Maths Tricks: Simple Interest 

Simple Interest (S.I.): It is a very easy method of calculating interests based on the Principal amount of a deposit. Let Principal = P, Rate = R% (p.a.) and Time = T years. Then Simple Interest = PRT/100

AFCAT Maths Tricks: Profit and Loss

  • Cost Price is the price at which a product is purchased. (C.P)
  • Selling Price is the price at which a product is sold.(S.P)
  • Profit or Gain: If S.P is greater than C.P then the seller is having a profit or gain.
  • Loss: If S.P is less than C.P then the seller is having a loss.
  • Loss or gain is always based on C.P.
  • Profit = (S.P.) – (C.P.)
  • Loss = (C.P.) – (S.P.)
  • Suppose, a product is sold at a profit of 10%, then S.P. = 110% of C.P.
  • Suppose, a product is sold at a loss of 20% then S.P. = 80% of C.P.

Try to practice these formulas every day and solve the numerical ability problems in your AFCAT exams. These are the basic mathematical formulas that are relevant for every type of competitive exam.
