There are not many straightforward AFCAT test mathematical capacity maths recipes you should keep on your fingertips to tackles the science question of AFCAT question paper. AFCAT test paper comprises of extremely essential science questions and these equations will assist you with clearing them without any problem:

Decimal Fraction: A decimal part is a portion wherein denominator is a number force of ten. (The term decimals are ordinarily used to allude decimal portions). For the most part, a decimal portion is communicated utilizing decimal documentation and its denominator isn’t referenced unequivocally.

Change of a Decimal into Common Fraction: Put 1 in the denominator under the decimal point and addition with it however many zeros similar to the quantity of digits after the decimal point. Presently, eliminate the decimal direct and diminish the part toward its least terms.

- Some Basic Formulas:

- (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.

####
- Simplification: Rule of ‘BODMAS’ – This rule depicts the correct sequence in which the operations are to be executed, so as to find out the value of given expression. Full form of BODMAS is B – Bracket, O – of, D – Division, M – Multiplication, A – Addition and S – Subtraction. Thus, while solving or simplifying a problem, first remove all brackets, strictly in the order (), {} and ||. After removing the brackets, we will use the following operations strictly in the following order:
- of
- Division
- Multiplication
- Addition
- Subtraction.

####
- Average: Average = (Sum of observations/Number of observations)

####
- 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 5/9 with antecedent = 5, consequent = 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).

####
- Percentage:

- By a certain percent, we mean that many hundredths. Thus, x percent means x hundredths, written as x%. To express x% as a fraction: We have, x% = x/100
- To express a/b as a percent: We have, a/b = (a/b x 100)%
- Percentage Increase/Decrease: If the price of a commodity increases by R%, then the reduction in consumption so as not to increase the expenditure is: [(R/(100+R)) x 100]%. If the price of a commodity decreases by R%, then the increase in consumption so as not to decrease the expenditure is: [(R/(100-R)) x 100]%.
- Result on Population: Let the population of a town be P now and suppose it increases at the rate of R% per annum, then: population after n years = P (1+(R/100))n Population n years ago= P/ (1+(R/100))n
- Result on Depreciation: Let the present value of a machine be P. Suppose it depreciates at the rate of R% per annum. Then: Value of the machine after n years = P (1-(R/100)n , Value of the machine n years ago = P/ (1-(R/100)n, If A is R% more than B, then B is less than A by [(R/(100+R)) x 100] %, If A is R% less than B, then B is more than A by [(R/(100-R)) x 100] %

####
- Simple Interest:

- Principal: The money borrowed or lent out for a certain period is called the principal or the sum.
- Interest: Extra money paid for using other’s money is called interest.
- Simple Interest (S.I.): If the interest on a sum borrowed for certain period is reckoned uniformly, then it is called simple interest. Let Principal = P, Rate = R% per annum (p.a.) and Time = T years. Then Simple Interest = (P x R x T)/100

####
- Profit and Loss:

- Cost Price: The price, at which an article is purchased, is called its cost price, abbreviated as C.P.
- Selling Price: The price, at which an article is sold, is called its selling prices, abbreviated as S.P.
- Profit or Gain: If S.P. is greater than C.P., the seller is said to have a profit or gain.
- Loss: If S.P. is less than C.P., the seller is said to have incurred a loss.
- Gain = (S.P.) – (C.P.)
- Loss = (C.P.) – (S.P.)
- Loss or gain is always reckoned on C.P.
- Gain Percentage: (Gain %) = (Gain x 100) / C.P.
- Loss Percentage: (Loss %) = (Loss x 100) / C.P.
- Selling Price: (S.P.) = [ ((100 + Gain %)/100) x C.P.]
- Selling Price: (S.P.) = [ ((100 – Loss %)/100) x C.P.]
- Cost Price: (C.P.)= [ (100/(100 + Gain %)) x S.P.]
- Cost Price: (C.P.)= [ (100/(100 – Loss %)) x S.P.]
- If an article is sold at a gain of say 10%, then S.P. = 110% of C.P.
- If an article is sold at a loss of say, 20% then S.P. = 80% of C.P.
- When a person sells two similar items, one at a gain of say x%, and the other at a loss of x%, then the seller always incurs a loss given by: Loss % = (x/10)2
- If a trader professes to sell his goods at cost price, but uses false weights, then Gain % = [(Error/(True Wight – Error)) x 100 ]%
