• A. 15 and 144
• B. 8 and 154
• C. 28 and 134
• D. 18 and 144

Answer 1

The correct option is D 18 and 144

Let, the number be x
$\therefore$ Other number = 8x
Given, sum of the numbers is 162.

$\therefore$ x + 8x = 162
$⟹$ 9x = 162
$⟹$ x = $\frac{162}{9}$
$⟹$ x = 18

Other number = 8x = 8 $\times$ 18 = 144

$\therefore$ The numbers are 18 and 144.
