$\huge\bold{given}$

=> COST PRICE OF 20 PENCILS IS EQUAL TO THE SELLING PRICE OF 15 PENCILS

______________________________

LET,

=> THE COST PRICE OF 1 PENCIL :

$\huge\bold{ \: x \: rs \: }$
______________________________

STEP 1 :

=> TO FIND COST PRICE OF 20 PENCILS

______________________________

COST PRICE OF 20 PENCILS :

=> NO. OF PENCILS * COST OF 1 PENCIL

=> 20 * X

$\huge\bold{20x}$
______________________________

SELLING PRICE OF 15 PENCILS :

=> IS EQUAL TO :

=> COST PRICE OF 20 PENCILS :

$\huge\bold{20x}$

_______________________________

STEP 2 :

=> TO FIND SELLING PRICE OF 1 PENCIL

_______________________________

SELLING PRICE OF 1 PENCIL :

=> COST FOR PENCILS / NO. OF PENCILS

=> 20X / 15

$\huge\bold{4x \div 3}$
______________________________

STEP 3 :

=> TO FIND THE PROFIT ON 1 PENCIL

______________________________

PROFIT :

=> SELLING PRICE - COST PRICE :

=> ( 4X / 3 ) - ( X )

=> ( 4X / 3 ) - ( 3X / 3 )

$\huge\bold{\frac{x}{3}}$
_______________________________

STEP 4 ;

=> TO FIND THE PROFIT %

_______________________________

PROFIT %

=> PROFIT / CP * 100

=> ( X / 3 ) / X * 100

=> X / 3X * 100

=> 1 / 3 * 100

$\huge\bold{0.33\%}$
