Question

if the cost price of 12 pens is equal to the selling price of 16 pens find the loss percent

Answer 1

12 CP = 16 SP
Then SP/CP = 12/16
SP/CP = 3/4
means SP = 3 and CP = 4
so loss % =[ ( 3-4 )/4 ] × 100
(1/4) × 100 = 25%

Answer 2

Answer:

25%

Step-by-step explanation:

Given : the cost price of 12 pens is equal to the selling price of 16 pens

To Find: find the loss percent

Solution:

Let CP of 1 pen be x

So, CP of 12 pens = 12x

CP of 16 pens = 16x

Since we are given that SP of 16 pens = CP of 12 pens =12x

SO, loss % = $\frac{SP-CP}{CP} *100$

loss % = $\frac{16x-12x}{16x} *100$

loss % = $\frac{4x}{16x} *100$

loss % = $\frac{1}{4} *100$

loss % = $25$

Hence the loss percent is 25%
