### Gain Or Loss In The Whole Transaction:

**Question:**

A man sold two chairs at Rs. 1,200 each. On one he gained 20% and on the other he lost 20%. His gain or loss in the whole transaction is:

**Option A):**

1% loss**Option B):**

2% loss**Option C):**

15 gain**Option D):**

4% loss

**Correct Answer is Option D):**

4% loss

**Explanation:**

In the case where loss and gain percentage is common on same selling price, always a loss incurs in total deal. And this can be calculated by a short-cut:

Loss on total deal,

= (Common loss and gain percentage /10)2 = (20/10)2

= 4%

**Alternatively**, It can be also calculated through Graphic Change Method: This can be given by,

100==20% gain ==>120==20% loss==>96.

Loss = 4% (As 100 became 96).
