Question

solve the 6th sum fast. plz.​

Answer 1

Let the 2 numbers be x and y

We know that

xy= 36 and also

2/3 x= 6/5 y.

2/3 36/y = 6/5 y

24/y= 6y/5

y²= 20

Therefore y= 2√5

and x= 18/√5

Answer 2

$\huge{✯}$$\huge{\underline{\underline{\mathcal{\sf{Answer}}}}}$

$\huge{☞}$ First Number = $23\dfrac{1}{7}$

$\huge{☞}$ Second Number = $12\dfrac{6}{7}$

$\huge{✯}$ $\huge{\underline{\underline{\mathcal{\sf{Given}}}}}$

$\dfrac{2}{3}$ of first number is equal to $\dfrac{6}{5}$ of other number.

$\huge{✯}$ $\huge{\underline{\underline{\mathcal{\sf{Steps}}}}}$

Let first number be x.

Other number = 36-x

According to the question,

$\large{⇒}$$\dfrac{2}{3}$ of x = $\dfrac{6}{5}$ of (36-x)

$\large{⇒}$Sending x terms to LHS and constant terms to RHS,

$\large{⇒} \dfrac{2}{3} x = \dfrac{6}{5} (36 - x) \\ \\\large{⇒}\dfrac{2}{3}x = \dfrac{216}{5} - \dfrac{6}{5} x \\ \\ \large{⇒} \dfrac{2}{3} x + \dfrac{6}{5} x = \dfrac{216}{5} \\ \\\large{⇒} \dfrac{10x + 18x}{15} = \dfrac{216}{5} \\ \\ \large{⇒}28x = \dfrac{216 \times 15}{5} \\ \\\large{⇒} x = \dfrac{216\times 15}{5 \times 28} \\ \\ \: \large{⇒} x = \dfrac{162}{7} \\ \\\large{⇒} x = 23 \dfrac{1}{7}$

$\large{⇒}$Second Number = 36-$\dfrac{162}{7}$

$\large{⇒}$Second Number = $\dfrac{252-162}{7}$

$\large{⇒}$Second Number = $\dfrac{90}{7}$

$\large{⇒}$Second Number = 12$\dfrac{6}{7}$
