Answer 1

Hope u like my process
=====================
=> Let the number of articles bought be Rs x

=> Total cost price = Rs 900

=> Total articles remain undamaged = (x-5)

=> S.P for each article = Rs (900+ 2(x-5))

=> Profit = Rs 80

_______________________
$= > (900 + 2(x-5)) - 900 = 80 \\ \\ = > 2x - 10= 80 \\ \\ = > \boxed{ x = \frac{80+10}{2} = \underline{ \blue{ 45}}}$

Hence.. The required answer is 45
