Bankers’ Bounty – Quantitative Aptitude – Decimals and Fractions

Bankers Bounty Quantitative Aptitude

Dear Mockbankers

Today in Banker’s Bounty, you will get Decimal and Fraction concept and previous year questions.

Step 1: Watch the video prepared by MockBank’s expert.

Step 2: Read the concepts that follow.

Step 3: Put a timer before you solve the previous year questions on decimal and fraction in quiz and record how much time it takes you to solve it.

Step 4: Send us questions in comments section below which took maximum time and we will tell you a faster way to solve it.


Basic Concepts


A fraction is an expression that indicates the quotient of two quantities.

Examples of fractions: 1/2, 1/3, -8/5

A fraction has two parts, namely Numerator and Denominator.

Numerator is the number at the top of the fraction and denominator is the number at the bottom of the fraction.

For example, in the fraction 1/5, 1 is the numerator and 5 is denominator.

The denominator of a fraction cannot be zero


  1. Common Fraction:
    A common fraction (also known as Vulgar fraction and simple fraction) is a fraction in which both numerator and denominator are integers (As with other fractions, the denominator cannot be zero). Example 1/2, 1/5, 2/7 etc.
  2. Decimal Fraction:
    A decimal fraction is a fraction in which denominator is an integer power of ten. (The term decimals are commonly used to refer decimal fractions).
    Generally, a decimal fraction is expressed using decimal notation and its denominator is not mentioned explicitly. Example1/10 = 0.11/100 = 0.011/1000 = 0.001

    151/100 = 1.51

    Decimal fractions can also be expressed using scientific notation with negative exponents
    Example: 5.192 × 10−6 is a decimal fraction which represents .000005192.
  3. Conversion of decimal to fraction
     Put 1 in the denominator under the decimal point and annex with it as many zeros as is the number of digits after the decimal point. Now, remove the decimal point and reduce the fraction to its lowest terms.


0.5 = 5/10 = 1/2

0.75 = 75/100 = 3/4

1.25 = 125/100 = 5/4

Now that you have seen the video and taken the mock test , let us now start our timers and attempt the mock test below

Question 9 of 10

10. A fraction becomes 1/3 when 1 is subtracted from its numerator as well as from its denominator. If 1 is added to both its numerator and denominator it becomes 1/2 Find the fraction.

Question 10 of 10



  • revathy

    I am not able to understand qn no 9.could u pls explain in detail

    • srikar

      correct answer is 99962
      because remainder must be 2 if we divide the number by 3 or 5 or 8 or 12.

      99960 is a wrong answer..

      • Vaibhav

        Hi Srikar
        Thanks for pointing it out srikar.

    • Vaibhav

      Sure revathy. We will ask our expert to prepare a solution

    • Vaibhav

      Greatest five digit number =99999

      Divide 99999/120 = 833.325

      120*833= 99960

      99960+2 = 99962

      is your answer.
