Q:

If the cost price of a certain object doubles, then the loss gets tripled of what it was initially. The initial loss % was ?

A) 0 % B) 25 %
C) 75 % D) 50 %
 
Answer & Explanation Answer: D) 50 %

Explanation:

Let the cost price be x and selling price be y.
Loss = x – y

 

When the cost price doubles, the loss gets tripled.
So it becomes like this, 2x – y = 3(x-y)

=> x = 2y

 

Loss % = (loss/ C.P) x 100 = [(2y-y)/2y] x 100= 50 %
