Answer 2

Can I show it in simple way?

Let us take the vlaue of first chair as x

800/x = 120/100 (selling price % = orginal price 100% + 20% profit)

x = 800 x 100/120

= 80000/120 = 666.67

So the price of first chair = 666.67

Let us take the vlaue of first chair as y

800/y = 80/100 (Selling price % = orginal price 100% - 20% loss)

y= 800 x 100/80

= 80000/80 = 1000

So the price of first chair is 1000

Now total cost of 2 chairs = 666.67 + 1000 = 1666.67

The selling price of 2 chairs = 800 x 2 = 1600

The profit he made = 1666.67 - 1000 = Rs 66.67

In % = 66.67 x 100 /1666.67 = 4.0007 % he made profit

I hope it helped you
