Half of a number is 12. What is $\dfrac{3}{4}$ of the same number ?

vedic methods of multiplication history of mathematics maths

  1. 24

  2. 36

  3. 9

  4. 18

Show answer
Correct Option: D
Explanation:

Let the number be $x$.

 

Since,

$ \dfrac{x}{2}=12 $

$ x=24 $

 

Since,

$ \Rightarrow \dfrac{3}{4}\times 24 $

$ \Rightarrow 18 $

 

Hence, this is the answer.

Sonia talked on the telephone to two friends. She talked to Shivani for $\displaystyle{\dfrac{1}{4}}$ hour to Geetika for $\displaystyle{\dfrac{1}{3}}$ How much time did Sonia spend on the telephone ?

  1. $\displaystyle{\dfrac{1}{6}}$

  2. $\displaystyle{\dfrac{2}{7}}$

  3. $\displaystyle{\dfrac{5}{12}}$

  4. $\displaystyle{\dfrac{7}{12}}$

Show answer
Correct Option: D
Explanation:

Sonia talked to Shivani for $=\dfrac{1}{4}$ hour

Sonia talked to Geetika for $=\dfrac{1}{3}$ hour

She spend time on the telephone will be
$=\dfrac{1}{4}+\dfrac{1}{3}$
$=\dfrac{7}{12}$ hour

Hence, this is the answer.

Victor can throw a ball 50$\displaystyle{\dfrac{3}{5}}$ feet. Parth can throw the same ball 48$\displaystyle{\dfrac{1}{3}}$ feet. How much farther can Victor throw the ball than Parth ? 

vedic methods of multiplication history of mathematics maths

  1. 2$\displaystyle{\dfrac{2}{15}}$ feet

  2. 2$\displaystyle{\dfrac{4}{15}}$ feet

  3. 2$\displaystyle{\dfrac{3}{5}}$ feet

  4. 2$\displaystyle{\dfrac{4}{5}}$ feet

Show answer
Correct Option: B
Explanation:

Victor can throw a ball $=50\dfrac{3}{5}$ feet

Parth can throw the same ball $=48\dfrac{1}{5}$ feet

Difference,
$=50\dfrac{3}{5}-48\dfrac{1}{3}$
$=\dfrac{253}{5}-\dfrac{145}{3}$
$=\dfrac{253}{5}-\dfrac{145}{3}$
$=\dfrac{34}{15}$
$=2\dfrac{4}{15}$ feet

Hence, this is the answer.

If $60$% of $\cfrac{3}{5}$ of a number is $36$, then the number is:

vedic methods of multiplication history of mathematics maths

  1. $80$

  2. $100$

  3. $75$

  4. $90$

Show answer
Correct Option: B
Explanation:

Let the number be $x$. Then
$60$% of $\cfrac{3}{5}$ of $x=36$
$\Rightarrow$ $\cfrac{60}{100}\times \cfrac{3}{5}\times x=36$
$\Rightarrow$ $x=(36\times \cfrac{25}{9})=100$
$\therefore$ Required number $=100$

Identify the larger fraction between $\dfrac{4}{5}, \dfrac{5}{9}$ using Vedic mathematics.

vedic methods of multiplication history of mathematics maths

  1. $\dfrac{4}{5}$

  2. $\dfrac{5}{9}$

  3. Both are equal

  4. None of these

Show answer
Correct Option: A
Explanation:

5/4 , 5/9
Difference of cross product = 45 - 20 = 25
If the difference of the cross product is positive then the first fraction is larger.
hence 5/4 is larger.
