Question

a dealer offer 20% discount if the selling price of article is 216 then what is the market price of articles ​

Answer 1

Answer:

8

Step-by-step explanation:

For answering such questions here I give you a short cut method -

Gain or loss percent = X + Y +(X×Y)/100

For increase use positive sign and for decrease use negative sign.

So here, X = +20%

And Y = -10% negative as it is discount

Put the values of X and Y in the above formula, if solution is positive it is gain and if it is negative it is loss

=20 +(-10) +(20×-10)/100

=20 -10 -200/100

=20–10–2

=8

It is positive so there will be profit of 8% in this transaction.
