Answer 2

$\large\bf\underline{Given:}$

72 is divided into two numbers in ratio 2:7.

$\large\bf\underline{To\:Find:}$

The two numbers

$\large\bf\underline{Solution:}$

Let the two numbers be 2x and 7x.

Therefore, sum of these to numbers will be equal to 72.

$\implies2x + 7x = 72$

Lets solve the equation to find the value of x.

$\implies 9x = 72 \\ \implies x = \frac{72}{9} \\ \implies x = 8$

Therefore, the two numbers are

$2x = 2(8) = 16 \\ </p><p>7x = 7(8) = 56$

Hence,Option (B) is correct.
