profit is sp(selling price) -cp(cost price)

12(sp-cp)=4sp

8sp=12cp

sp/cp=12/8

profit percentage is( (sp-cp)/cp )100

or (sp/cp -1)100

(12/8 -1)100

(4/8)100

Ans 50%

Answer:

Step-by-step explanation:

Let Rs x be the SP of each pen

SP of 12 pens = ₹ 12x

Gain=SP of 4 pens = ₹ 14x

CP = SP -Gain

12x - 4x = ₹ 8x

Gain % = Gain /CP ×100

4x/8x ×100%

ANSWER =50%
