Exercise: Profit And Loss

The cost price of 20 articles is the same as the selling price of x articles. If the profit is 25%, then the value of x is:

Answer: B

Let C.P. of each article be Re. 1 C.P. of x articles = Rs. x.

S.P. of x articles = Rs. 20.

Profit = Rs. (20 - x).

Alfred buys an old scooter for Rs. 4700 and spends Rs. 800 on its repairs. If he sells the scooter for Rs. 5800, his gain percent is:

4	4	%
	7

5	5	%
	11

10%

12%

Answer: B

Cost Price (C.P.) = Rs. (4700 + 800) = Rs. 5500.

Selling Price (S.P.) = Rs. 5800.

Gain = (S.P.) - (C.P.) = Rs.(5800 - 5500) = Rs. 300.

Gain % =		300	x 100	%	= 5	5	%
		5500				11
