Question

a shopkeeper gains 20 % whilw biying the goods and 30% while selling them .find his total gain percent ?​

Answer 1

Answer:

56%

Step-by-step explanation:

Let the C.P. of the goods be Rs. 100. 

As the shopkeeper gains 20% at the time of buying, the shopkeeper buys the articles worth Rs. 120.

∴ S.P. = Rs. (120×(100+30))/100

= Rs. (120×130)/100

= Rs. 156

∴ % gain =(156−100)/100 ×100=56 %.
