Answer 2

$\huge{\boxed {\tt{Solution : }}}$

Given :

• $\sf {\dfrac{b}{10} = \dfrac{3}{5}}$

To Find :

• Solve the proportion.

$\tt {We\: can\: write\: \dfrac{b}{10} = \dfrac{3}{5}\:as:}$

$\longrightarrow \sf{b : 10 : :3 : 5}$

$\tt{ \because {Product\:of \:extremes=Product\:of \:means}}$

$\sf { : \implies{ b:10 : :3 :5 }} \\ \\ \sf { : \implies{b \times 5 = 10 \times 3 }} \\ \\ \sf { : \implies{5b = 30}} \\ \\ \sf { :\implies{b = \dfrac{30}{5}}} \\ \\ \sf { : \implies{\boxed{\tt{b = 6}}}}$

$\bf{\therefore{The\: value\:b\:is\:6.}}$

$\rule{307}{2}$
