Question

Prakash bought 20 pens at 15 per pen and 15 pens at 18 per pen. He sold all the pens at 17 per
his gain or loss percent in the whole transaction.​

Answer 1

Step-by-step explanation:

C.P = 20*15 = 300

C.P2 = 15*18 = 270

Total C.P = 570

Total pens sold = 20+15 = 35

S.P = 35*17

= 595

So, profit % = 25/570 = 100

= 4.38 %
