Q11.	The profit earned by selling an article for Rs.744 is double the loss incurred when the same article is sold for Rs.240. What would the selling price of the article if it is sold at 15% profit ?

1)	Rs.472.20	2)	Rs.469.80
3)	Rs.468.20	4)	Rs.479.20
5)	None of these

Answer : Rs.469.80
Explanation : Let, the C.P be Rs.x.

Then, according to the question, 744 - x = 2(x-240)

or 744 - x = 2x - 480

or 3x = 744 + 480 =1224

or x = 1224/3 = Rs.408

So, required S.P = 408 X (115/100 ) = Rs.469.20

Q12.	A tradesman bought a second-hand car for Rs. 6000 and spent Rs. 500 on its repair. He sold it for Rs. 7020. What is his percentage of profit after selling it ?

1)	5%	2)	6%

Explanation : Total cost price of the car after repair = Rs.(6000+500 ) = Rs.6500

S.P = Rs.7020

Profit = Rs.7020 - Rs.6500 = Rs.520

So, percentage of profit = (520/6500) x 100 = 8%

Q13.	A shopkeeper marked an article at 40% above the cost price. He, then sold it after offering a discount of 30%. If he made a loss of Rs.60, find his selling price (in Rs.)

1)	Rs.2500	2)	Rs.2840
3)	Rs.2940	4)	Rs.3000
5)	None of these

Answer : Rs.2940
Explanation : Let, the C.P be Rs.x.

After, 40% above the CP, the M.P be 1.4x.

Now, he sells it at 30% discount.

Then, the S.P would be (1.4x ) x 70/100 = 0.98x

So, x - 0.98x = Rs.60

Or x = Rs.3000

Therefore, the selling price is 3000 x 98/100 =Rs.2940
