Answer 2

★ Question:-

If 8,15,24, are in proportion find the fourth proportional

★ Solution:-

We have :-

8 : 15 :: 24 : ?

Let us assume the fourth proportion x

According to the question :-

$\large{ \sf{8 : 15 : : 24 : x}}$

We know ,

$\pink{ \bigstar} \underline{\boxed{ \large { \sf{Extreme \: Term = Middle \: term}}} } \red{ \bigstar}$

So,

$\bf{ \large{8 \times x = 15 \times 24}}$

$\bf{ \large{8x = 360}}$

$\large{ \bf{x = 360 \div 8}}$

$\large{ \bf{x = \underline{ \red{ \boxed{40}}}}}$

The fourth proportion is 40.
