Answer 2

Question:-

find the value x in the proportion 9:5::36:(x-3)

Answer:-

• The value of x is 23.

To find:-

• Value of x

Solution:-

According to question,

$\large{ \tt : \implies \: \: \: \: \: 9 : 5 : : 36 : (x -3 )}$

$\large{ \tt : \implies \: \: \: \: \: \frac{9}{5} = \frac{36}{x - 3} }$

After cross multiplication,

$\large{ \tt : \implies \: \: \: \: \: 9 \times (x - 3) = 36 \times 5}$

$\large{ \tt : \implies \: \: \: \: \: 9x - 27 = 180}$

$\large{ \tt : \implies \: \: \: \: \: 9x = 180 + 27}$

$\large{ \tt : \implies \: \: \: \: \: 9x = 207}$

$\large{ \tt : \implies \: \: \: \: \: x = 23}$

Hence,

The value of x is 23.
