56%

Step-by-step explanation:

Given :A shopkeeper gains 20% while buying the goods and 30% whole selling them.

To Find : find his total gain percent

Formula of net gain % = $a+b+\frac{ab}{100}$

a = 20

b = 30

Substitute the values :

Net gain % = $20+30+\frac{20 \times 30}{100}$

                   = $20+30+\frac{600}{100}$

                   = $20+30+6$

                   = $56$

Hence his total gain percent is 56%
