Answer:

\huge\underline\bold {Answer:}

Let the C.P. (cost price) of the goods be 100 rupees. As the shopkeeper gains 20% at that time of buying, the shopkeeper buys the articles worth 120 rupees.

Therefore S.P. (selling price)

 =  \frac{120(100 + 30)}{100}   \\  =  \frac{120 \times 130}{100}  = 156

Therefore percentage gain

 =  \frac{(156 - 100)}{100}  \times 100 \\  = 56\%

Let A = 20% & B=30%.

Total profit = A+B+AB/100

=20+30+20*30/100

= 20+30+ 6

=> 56%✔✔
