C. P. Of 6 pencils = S. P. Of 5 pencils
Sp, C. P. / S. P. = 5/6.

Let S. P. Be Rs. 6x
And, C. P. Be Rs. 5x

Gain = Rs. (6x-5x) = Rs. x
Gain% = {(Gain/C. P.)×100%}
= {(x/5x)×100%}
= 20% [Ans.]

Answer 2

Question:-

if the cost price of 6 pencils is equal to the selling price of 5 pencils ,find the gain percent.

Method of Solution;-

Let the CP of 6 pencils = Rs x

Now, 

CP of 1 pencil = (x/6)

Now, 

SP of 5 pencils = SP of 1 pencil = (x/5)

Here,

 SP > CP, 

Now,

gain = SP−CP = x/5−x/6 

=) 6x−5x/30 = x/30

Again,

Gain% = [gain/CP×100]

=> X/30x × 100

=> 100/30

=> 10/3

=>3.33%

Hence, Gain Percentage = 3.33%
