Answer 1

PLEASE MARK MY ANSWER AS BRAIN LIST

Answer 2

Given,

cp of 6 = sp of 5

let the cp of 1 pen be ₹1

therefore

cp of 6 = ₹6

sp of 5 = ₹6 (as cp of 6 = sp of 5)

cp of 5 = ₹5 (as we have taken the cp of 1 pen as ₹1, the cp of 5 pens will be ₹5)

gain = sp - cp

gain = ₹6 - ₹5

gain = ₹1

gain% :

$\frac{1}{5} \times 100$

gain% = 20%

hope it helps!!

have a great day!!
