Question

A shopkeeper gains 30% while buying goods and 20% while selling them. What is the total
percentage of gain?​

Answer 1

Answer:

it's 50 percent gain to him

Answer 2

Answer:

44℅

Step-by-step explanation:

let

the c. p. of the goods be 100 units

&

the shopkeeper gets it on 30℅ profit so his purchase price = 100 - 100×30℅ = 70 units

now

he sells it on 20℅ profit

so

20℅ of 70 = 14 units

now his overall gain =>

30 units + 14 units = 44 units

in percentage = gain/c.p. × 100

=> gain ℅ = 44/100 × 100 = 44℅
