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: Option

Explanation:

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).

		20 - x	x 100 = 25
		x

2000 - 100x = 25x

125x = 2000

x = 16.

CP * 20 = SP * X,
25 % PROFIT MEANS (CP+CP*25/100)=1.25 CP
NOW YOU CAN WRITE SP= 1.25 CP,
CP*20=1.25 CP * X
X=20/1.25
X= 16

Let c.p. IS a rs.
Then C.P. of 20 articles =20a = S.P. of x articles
So S.P. of 1 articles=(20.a)/x
So Gain=((20.a)/x)-(a)=a(20-x)/x
Now as Gain%=gain*100/C.P= ((a(20-x)/x)*100)/a=(20-x)*100/x
25=((20-x)/x)*100 => 25x=2000-100x => x=2000/125 = 16
Hence Proved :)
