A bought an article for ₹4,800 and sold it at a loss of 30%. With this amount, he bought another article and sold it at a gain of 60%. What was his overall gain/loss?

Gain 12%

Let the cost price of the article = 100

Loss = 30%

Then the selling price of the article = 70% of 100 = 70

He bought the another article at the same price and sold it at a gain  of 60% means,

CP of another article = 70

Profit = 60% 

Then the SP of the another article = 160% of 70 = 112

According to the question,

Profit = 112 - 100 = 12

Profit% = 12 × \(\frac{100}{100}\) = 12%

Note= There is no use of actual amount in this type of questions.
