Question

1)     An article bought for Rs 350 is sold at a profit of 20%. Find its selling price.​

Answer 1

Answer:

Rs420

STEP BY STEP EXPLANATION:

Cost of Article= Rs350

Selling Price at Profit=

(Cost Price + Profit%×Cost price)

So, SELLING PRICE:

=350+(20/100×350)

=350+(1/5×350)

=350+(350/5)

=350+70

=420

Answer 2

Profit=20%

=>S.P=120%of C.P

i.e., selling price =120/100×350

=rs 420

Alternative method:-

C.P=RS 350

and profit =20% of RS 350

=20/100×350

=rs 70

Selling price= Cost price + Profit

= RS (350 + 70).

=RS 420
