Question

Answer 1

hii dear !! here is your answer hope it helps you

Answer 2

Let CP of one article be 16
Then CP of 10 articles = 160

CP of 10 articles = SP of 8 articles = 160
SP of one article = 160/8 = 20

Gain = SP - CP
= 20-16
= 4
Gain% = gain/CP × 100
= 4/16 × 100
= 100/4
= 25%

Hope it helps
