\huge \boxed{\mathbb{QUESTION} \downarrow}

  • Revathi's age is 1/3 of her mother's age. If their difference in age is 24 years, find Revathi's age.

\large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}

Given,

  • Mother's age = x
  • Revathi's age = 1/3 x = ?
  • Difference in their age = 24 years ⇨ x - 1/3 x = 24.

Now, let's solve this question using the above equation which we just formed.

\sf \: x -  \frac{1}{3}x  = 24 \\

Combine x and \sf\:-\frac{1}{3}x to get \sf\frac{2}{3}x.

\sf\frac{2}{3}x=24  \\

Multiply both sides by \sf\frac{3}{2}, the reciprocal of \sf\frac{2}{3}.

\sf \: x=24\times \left(\frac{3}{2}\right)

Express \sf24\times \left(\frac{3}{2}\right) as a single fraction.

\sf \: x=\frac{24\times 3}{2}  \\

Multiply 24 and 3 to get 72.

\sf \: x=\frac{72}{2}  \\

Divide 72 by 2 to get 36.

\boxed{ \bf \: x=36 }

We now have the age of Revathi's mother (x) = <u>36 years</u>. Now, let's find Revathi's age ⇨ \sf\:(\frac{1}{3}x)

\rightarrow \sf \:  \frac{1}{3} x  \\  \rightarrow \sf \: \frac{1}{3}  \times 36 \\  \rightarrow \sf \: \frac{1}{ \bcancel  3}  \times  \bcancel{36} \\  \rightarrow \sf \:1 \times 12 \\  =    \boxed{\boxed{\bf \: 12}}

  • So, Revathi is <em><u>1</u></em><em><u>2</u></em><em><u> </u></em><em><u>years </u></em><em><u>old.</u></em>

Jasmine wants to use her savings of $1,128 to buy video games and music CDs. The total price of the music CDs she bought was $72
inysia [295]
For the answer to the question above, she can buy 24 video games

Because she bought a CD on her savings, we must deduce the cost of the CD from her 1,128 savings 
1128 - 72=1056

Then just divide the difference to how much each videogame cost
1056 / 43 = 24

So the answer is she can buy 24 videogames.
