Answer 2

Hey!! Your answer-

If p + q = 10
pq = 5

$\frac{p}{q} + \frac{q}{p} = \frac{ {p}^{2} + {q}^{2} }{pq}$
$\frac{ {(p + q)}^{2} - 2pq }{pq} \: eq.1$
Put p + q = 10. and pq = 5 in eq. 1.
$\frac{ {(10)}^{2} - 2 \times 5 }{5}$
$\frac{100 - 10}{5} = \frac{90}{5}$
$\frac{90}{5} = 18$
Hence, the value of
$\frac{p}{q} + \frac{q}{p} = 18$
Hope it helps!!
