Question
Anjali sold a gadget at a profit
of 30%, while Rahul sold the same gadget at a profit of 28%. If Anjali earned Rs. 50 more than Rahul, find the cost price of the gadget.Solution
ATQ,
Let the cost price of the gadget be Rs. 'y.' Selling price of the gadget for Anjali = Rs. '1.30y.' Selling price of the gadget for Rahul = Rs. '1.28y.' According to the question: 1.30y−1.28y=50 0.02y=50 So, y=2500 Therefore, the cost price of the gadget is Rs. 2,500.
