Question

if rakesh sold 5 pencils and the amount of 4 pencils is same what is the gain.​

Answer 1

Answer:

Step-by-step explanation:

Cost price :

5 pencils cost Rs 4

So, Cost price of 1 pencil =Re 4/5

Selling price:

4 pencil cost=Rs 5

Selling price of 1 pencil =Rs 5/4

So, %Gain= {(S.P.-C.P)/ C.P.}×100

={(Rs 5/4)-(Rs 4/5)/Rs 4/5}×100

={(25–16)/20/4/5}×100

=(45/80)×100=225/4=56.25

Answer 2

Answer:

let the cost of 5 pencils be x

cost of 4 pencils=4x/5

but SP of 4 pencils=x

So gain= x-4x/5= x/5

gain percentage=(x/5) / (4x/5) ×100 %

=x/5× 5/4x × 100 %

=1/4 ×100 %

=25%
