Aptitude Questions and Answers:

1. Number Systems:

Natural Numbers: The numbers which are used to count the objects known as natural numbers. Whole Numbers: In the natural numbers set if we include number 0 then the resulting set will be known as whole numbers….more

2. HCF and LCM:

  • Factors and Multiples: When the number ‘m’ divides another number ‘n’ exactly, then we can say that ‘m’ is a factor of ‘n’. In this case, ‘n’ is called a multiple of ‘m’.
  • HCF (Highest Common Factor): The HCF of two or more than two numbers is the greatest number that divides each of them exactly. Methods to find HCF of a given number….more

3. Percentages:

What is Percentage? Percent is made of two words per and cent. Meaning of percent is “per hundred”. Sign of percent is %. To express x% as a fraction we have x% = x/100. Thus, 20% = 20/100 = 1/5; 54% = 54/100 = 27/50, etc….more

4. Profit, Loss and Discount:

  • Profit – If selling price of any item is more than the cost price of the item then there is a profit on the selling the item. Profit = Selling Price – Cost Price
  • Loss – If selling price of any item is less than the cost price of the item then there is a loss on the selling the item. Loss = Cost Price – Selling Price
  • Discount – Sometimes shopkeeper gives you some rebate on items on selling to their customers. This rebate is known as discount and discount is known as rebate….more

5. Speed, Time and Distance:

  • Speed = Distance/Time , Time = Distance/Speed, Distance = Speed * Time
  • x km/hr = (x* 5/18) m/sec
  • x m/sec = (x* 18/5) km/hr
  • If the ratio of the speeds of A and is a:b, then the ratio of the time taken by them to cover the same distance is 1/a : 1/b or b:a….more

6. Time and Work:

  • If A can do a piece of work in n days, then A’s 1 day’s work = 1/n
  • If A’s 1 day’s work = 1/n, then A can finish the work in n days…..more

7. Averages:

What is average? Average is defined as the ratio of sum of all observations in a group to the number of observations in the group…..more

8. Ratio and Proportion:

What is ratio? The ratio of two quantities a and b in the same units, is the fraction a/b 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.

What is proportion? The equality of two ratios is called proportion. If a : b = c : d, we write, a : b : : c : d, then d is called the fourth proportion. Here a and d are called extremes, while b and c are called mean terms…..more

9. Simple and Compound Interest:

Principal: The money borrowed out for a certain period is called the principal or the sum.

Interest: Some extra money paid for using other’s money is called interest.

Simple Interest (S.I.): When the sum borrowed for a certain period is computed uniformly, then it is called simple interest.

Compound Interest: The compound interest is interest calculated on the initial principal which also includes all of the accumulated interest of previous period of a deposit. The borrower and the lender agrees to fix up a certain unit of time, say yearly or half-yearly or quarterly to settle the previous account……more

10. Boats and Streams:

Boats and Streams: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 of downstream = (u + v) km/hr
Speed of upstream = (u – v) km/hr………more

11. Partnership:

What is Partnership? The form of association of two or more persons, who contributes resources like money together in order to carry on a business, is known as partnership. It is of following two types:

  • Simple Partnership: A partnership in which capitals of the partners are invested for the same time is known as simple partnership. The profits or losses are divided among the partners in the ratio of their investment……more

12. Linear Equations:

What are Linear Equations? An equation is a statement of equality of two algebraic polynomial involving one or more variables. The expression of the form Ax + B, where A and B are real numbers and A ≠ 0, is a linear polynomial and equation involving only linear polynomial are called linear equations……more

13. Problems on Ages:


1. Sanjay is younger than Raj by 4 years. If their ages are in the respective ratio of 7:9, how old Sanjay is?

A)    14 years

B)    18 years

C)    28 years

D)    24.5 years

E)    None of these……more

14. Problems on Trains:

  • a km/hr = a*(5/18) m/s
  • a m/s = a*(18/5) km/hr
  • Time taken by a train of length l metres to pass a pole or a standing man or a signal post is equal to the time taken by the train to cover l metres.
  • Time taken by a train of length l metres to pass a stationary object of length b metres is the time taken by the train to cover (l + b) metres…….more

15. Probability:

  • Event: Any subset of a sample space is called an event.
  • Probability of Occurrence of an Event: Let S be the sample space and let E be an event……more

  • If a pipe can fill a tank in x hours, then:

part filled in 1 hour = 1/x….more

17. Trigonometry:

Trigonometry: In a right angled OAB, where ∠BOA = θ ,

i. sin(θ) = Perpendicular / Hypotenuse     = AB / OB ;

ii. cos(θ) = Base / Hypotenuse  = OA / OB ;

iii. tan(θ) = Perpendicular / Base = AB / OA ;…….more

18. Measurements:

• Rectangle

Area = lb

Perimeter = 2(l+b)

• Square

Area = a×a

Perimeter = 4a…….more

19. Statement and Argument:
