Question

A number is 2/3 a other number if there sum is 70. Find the number

Answer 1

$\large \ulcorner \pink {Answer} \lrcorner$ :-



Let the number be x

$\dfrac{2}{3}$ of a number = $\dfrac{2}{3}$x

Their sum = 70


According to the question,

x + $\dfrac{2}{3}$x = 70

$\dfrac{3x + 2x}{3}$ = 70

$\dfrac{5x}{3}$ = 70

5x = 70 × 3

5x = 210

x = $\dfrac{210}{5}$

x = 42




$\therefore{}$ $\texttt{The number is 42}$

Answer 2

Answer:

42

Step-by-step Explanation:

Let the number be x.

On reading the question carefully we also get the following informations,

Another Number = ( 2 / 3 ) * x = 2x / 3

The sum of these two numbers = 70

But, sum of these two numbers = x + ( 2x / 3 )

Hence, on analysing the above informations we derive the following relation,

x + ( 2x / 3 ) = 70

( 3x + 2x ) / 3 = 70

5x / 3 = 70

5x = 3 * 70

5x = 210

x = 210 / 5

x = 42

Therefore,

The number is 42.
