Question

The cost price of 6 pencils is equal to the selling price of 8 pencils. Find the loss per cent.
​

Answer 1

Given :-

The cost price of 6 pencils is equal to the selling price of 8 pencils.

Solution :-

CP of 6 pencils = SP of 8 pencils

Let the CP of 1 pencil be 1 Rupee

Therefore ,

CP of 6 pencils be Rs.6

According to the question,

CP of 6 pencils = SP of 8 pencil

Rs. 6 = SP of 8 pencils

Therefore,

SP of 1 pencil = 6/8 = 0.75

Now, Calculating Loss

CP - SP = Loss

Here,

CP of 1 pencil - SP of 1 pencil = Loss

Put the required values,

1 - 0.75 = 0.25

Hence , He gain loss of Rs 0.25

Now, Calculating Loss %

Loss / CP * 100

Put the required values in the formula,

0.25 / 1 * 100 = 25%

Hence, The Loss % = 25% $.$
