Question

rohon purchase a TV set for rs 4500.he sells it to raj at a profit of 10%.after some days raj sells the TV set back to rohon at a loss of 10%.find rohon saving in whole transcation

Answer 1

Rohan buy tv of rupees 4500
Profit of rohan after selling it to raj=10/100*4500=450₹
It means rogan sells it to raj at 4500+450=4950₹
Now,loss of raj in selling it back to rohan is 10%
So,10/100*4950=loss of raj=495₹
Thus,the selling price of tv back to rohan is 4950-495=4455₹
Saving of rohan,=4500-4455=45₹

Answer 2

Original Price = Rs 4500

Find the price he sold it Raj:

Profit = 10% x 4500 = 0.1 x 4500 = Rs 450

Price = 4500 + 450 = Rs 4950

Find the price Raj sold back to him:

loss =  10% x 4950 = 0.1 x 4960 = Rs 495

Price = 4950 - 495 = Rs 4455

Find Rohan's saving:

He sold it at Rs 4950 and bought it back at Rs 4450

4950 - 4450 = Rs 500

Answer: Rohon now has the TV and a saving of Rs 500 from the transaction.
