Answer 2

Answer:

Question:

Find the fourth proportion to 7 , 21 , 24

Solution:

7:21 :: 24:x

( I have taken x as the fourth number )

$\frac{7}{21} = \frac{24}{x}$

Now,

$7 \times x \: = 24 \times 21$

$x \: = \frac{24 \times 21}{7}$

[ Performing the sum ]

x = 72

So, the required number is 72
