Question

the cost price of 20 chocolate is equal to the selling price of 25 bars of chocolate find the loss persent

Answer 1

20 x Cost Price = 25 x Selling Price
Selling Price = ( 20 x Cost Price ) / 25
Selling Price = ( 4 x Cost Price ) / 5 (1)

Loss = Cost Price - Selling Price
Loss = Cost Price - ( 4 x Cost Price ) / 5 [ By (1) ]
Loss = ( 5 - 4 )Cost Price/ 5
Loss = Cost Price/ 5

Loss % =( Loss x 100 ) / Cost Price
Loss % =( ( Cost Price/ 5 ) x 100 ) / Cost Price
Loss % =( Cost Price x 20 ) / Cost Price
So, Loss % = 20%

Answer 2

Answer:

Step-by-step explanation:

let SP of 1 chocolate be =1

25 chocolate = 25 rupees

cp of 20 =25

per bar 25/20=5/4= 1.25

cp> sp =loss

=0.25 rupees is loss

l% 0.25/1.25*100 = 25/1.25 =20%

so the loss percent is 20
