A mobile phone and a tablet were sold at a profit of 10% and at a loss of 8% respectively. If the cost price of the mobile is 1.5 times that of the tablet, what is the overall profit percentage earned by selling both the articles
Explanation:
Let the cost price of the tablet = INR x
and cost price of the mobile = INR 1.5x
Total cost price of both the articles
= x+15x= 2.5x
Total selling price of both the articles
= x×92/100+1.5x×110/100
=INR 2.57 x
Gain = (2.57-2.50)x = 0.07x
∴ Required gain percentage = 0.07/2.5×100
=2.8%
