Question

Find the selling price, when the marked price is 800 and discount is 20%​

Answer 1

Answer:

₹640

Step-by-step explanation:

[Selling price] SP= a

[Marked price] MP= 800

Discount = 20%

So, first take out 20% of 800, then subtract the answer from 800

20/100 x 800 = ₹160

Now subtract

800-160= ₹640

Answer 2

Given:

Marked Price (M.P.) = ₹800

Discount% = 20%

To find:

The Selling Price (S.P.)

______________________________

Solution:

As we know that,

$Discount \%=\frac{Discount}{M.P.}$ × 100%

Also,

Discount = M.P. - S.P.

So, we can write the new formula as,

$Discount \%=\frac{M.P.-S.P.}{M.P.}$ × 100%

On substituting the values in the formula,

$20 \%=\frac{800-S.P.}{800}$ × 100%

$20 \%=\frac{800-S.P.}{8}$

20×8 = 800 - S.P.

160 = 800 - S.P.

S.P. = 800 - 160

$\boxed {\sf {\pink {S.P. = Rs. 640}}}$

Final answer:

The S.P. is ₹640.
