Question

Soumya bought a pen for rupees 20 and sold it with 10% profit of it. find its selling price

Answer 1

SOLUTION :

The cost of the pen (C.P) = Rs 20    (given)

The profit% = 10% in S.P    (given)

To be found :-

Selling Price (S.P)

We know that,

⇒ $\bf S.P = C.P \times \frac{(100+Profit\%)}{100}$

⇒ $\bf S.P = 20 \times \frac{(100+10)}{100}$

⇒ $\bf S.P = 22$

∴ Selling Price (S.P) is Rs 22

Answer 2

CPof a pen=20
Profit%=10
SP of pen= CP×(100+PROFIT%/100)
= 20×(100+10/100)
= 20×(110×100)
=22 rupees
