Question

A shopkeeper sold to electronic gadgets for rupees 4000 each the shopkeeper made a loss of 12% on one and a profit of 10% on the other find the overall gain or loss ​

Answer 1

Answer:

Let us take the vlaue of first electroic gadgets as x

4400/x = 88/100 (Selling price = orginal price 100% - 12% loss)

x = 4400 x 100/88

= 440000/88 = 5000

So the price of first electronic gadgets is Rs. 5000

Let us take the vlaue of second electronic gadget as y

4400/x = 110/100 (Selling price = orginal price 100% and 10% profit)

x = 4400 x 100/110

= 440000/110 = 4000

So the price of second electronic gadget is Rs. 4000

Cost of two electronic gadgets = 4000 + 4000 = 8000

Selling price = 4400 + 4400 =8800

He made profit by 8800 - 8000 = Rs. 800

in % = 800 x 100 /8000 = 10 %
