Question

tell me some tips for studying profit,loss and discount

Answer 1

Hi Riona
From my point of view..for studying profit loss and discount..just go through the formulas by heart
For ur help I am mentioning all the main things of this chapter below
Cost price (CP) The amount for which an article is bought is called its cost price.


Selling price (SP) The amount for which an article is sold is called its selling price.


Profit or gain When (SP) > (CP) then there is a gain.
Gain = (SP) - (CP)


Loss When (SP) < (CP) then there is a loss.

Loss = (CP) - (SP).





Notes:

The gain or loss is always reckoned on the cost price

Calculating Profit Percent and Loss Percent



Profit and loss formulas for calculating profit% and loss%:

I. Gain = (SP) - (CP)

II. Loss = (CP) - (SP)

III. Gain% = (gain / CP × 100)%

IV. Loss % = (loss/ CP × 100)%

V. To find SP when CP and gain% or loss% are given:

● SP = [(100 + gain %) / 100] × CP

● SP = {(100 - loss %) /100} × CP

VI. To find CP when SP and gain% or loss% are given:

● CP = {100/(100 + gain %)} × SP

● CP = {100 /(100 - loss %)} × SP

OK
Thanks
Have a good day
