To find :

The value of x

Solution :

Step 1 of 2 :

Form the equation

Here it is given that 7 : 5 is in proportion to x : 35

So by the given condition

$\displaystyle \sf{ \frac{7}{5} = \frac{x}{35} }$

Step 2 of 2 :

Find the value of x

$\displaystyle \sf{ \frac{7}{5} = \frac{x}{35} }$

$\displaystyle \sf{ \implies 5x = 7 \times 35 }$

$\displaystyle \sf{ \implies x = \frac{7 \times 35}{5} }$

$\displaystyle \sf{ \implies x = 49}$

Hence the required value of x = 49
