Question

the cost of 12 pensis equal to thesp of 15 pens find the loss percent​

Answer 1

Answer:

through these question you consider opposite

sp = 12

cp = 15

then loss = 3

loss%= 3/15 ×100

=20% loss answer

second method

let cp of 12 pencil is rs =100

then cp of one pencil is = 100/12

now sp of 15 pens is rs = 100 because cost price of 12 pencil is is equal to the selling price of 15 pens.

sp of one pen is rs =100/15

cp of one pencil is rs 100/12

then cp is greater then loss happen

loss = cp - sp

now loss= 100/60

means loss= 5/3

loss%=loss/cp ×100

now ,

5/3 ×12/100 ×100

then the conquence is 20%
