Number System Type 3 : Fraction of numbers

Question 1:
A runner runs 1\frac{1}{4} laps of a 5 lap race. What fractional part of the race remains to be run?
एक धावक 5 लैप की दौड़ में 1\frac{1}{4} लैप दौड़ता है। दौड़ का कौन-सा भिन्नात्मक भाग चलाना बाकी है?

(1) \frac{15}{4}
(2) \frac{4}{5}
(3) \frac{5}{6}
(4) \frac{2}{3}

Show Answer and Solution
(1) \frac{15}{4}
Remaining race
= 5-1\frac{1}{4} laps
= 5- \frac{5}{4} laps
=\frac{15}{4} laps

Question 2:
\frac{1}{2} of \frac{3}{4} of a number is 2 \frac{1}{2} of 10.What is the number?
किसी संख्या का \frac{3}{4} का \frac{1}{2} 10 का 2 \frac{1}{2} है। संख्या क्या है?

(1) 50
(2) 60
(3) 66 \frac{2}{3}
(4) 56

Show Answer and Solution
(3) 66 \frac{2}{3}
Let the number is x.
According to the question
\frac{1}{2} of \frac{3}{4} of x = 2 \frac{1}{2} of 10
\frac{3x}{8}= \frac{5}{2}
x=\frac{ 5.10.8}{ 3. 2} = \frac{200}{3} = 66\frac{2}{3}

Question 3:
Difference between the reciprocal of a positive proper fraction and the fraction itself be frac{9}{20} , then the fraction is
यदि किसी धनात्मक उचित भिन्न के व्युत्क्रम और स्वयं भिन्न के बीच का अंतर frac{9}{20} है, तो भिन्न है

(1) \frac{3}{5}
(2) \frac{3}{10}
(3) \frac{4}{5}
(4) \frac{5}{4}

Show Answer and Solution
(3) \frac{4}{5}
The required fraction is \frac{4}{5} , because
=\frac{5}{4} \frac{4}{5}

Question 4:
In a class, there are ‘z’ students. Out of them ‘x’ are boys. What part of the class is composed of girls ?
एक कक्षा में ‘z’ विद्यार्थी हैं। उनमें से ‘x’ लड़के हैं। कक्षा का कौन सा भाग लड़कियों से बना है?

(1) \frac {x}{z}
(2) \frac {z}{x}
(3) 1- \frac {x}{z}
(4) \frac {x}{z} -1

Show Answer and Solution

Boys = x
Girls = z – x
Part of girls = \frac{z-x}{z}
= 1- \frac{x}{z}

Question 5:
0.393939 ……. is equal to
0.393939 ……. के बराबर है
(1) \frac{39}{100}
(2) \frac {13}{33}
(3) \frac {93}{100}
(4) \frac {39}{990}

Show Answer and Solution
