Question

All Formulas Of SP, CP, DISCOUNT, MRP FOR CLASS 8TH Ch- COMPARING QUANTITIES.

Answer 1

Profit or Gain = Selling Price - Cost Price = SP - CP Profit = CP×(Profit%) Loss = Cost price - Selling price = CP - SP Loss = CP×(Loss%) Profit % = SP−CP CP ×100= Profit CP ×100 Loss % = CP−SP CP ×100= Loss CP ×100 Important: Profit or Loss always calculated on Cost price Only. Discount = Marked price - Selling Price = MP - SP

Answer 2

 SP= The price, at which an article is sold, is called its selling prices
 CP= the price, at which an article is purchased, is called its cost price
DISCOUNT=marked price- sale price
MRP = maximun retail price
Profit or Gain: If S.P. is greater than C.P., the seller is said to have a profit or gain.
Loss: If S.P. is less than C.P., the seller is said to have incurred a loss.
IMPORTANT FORMULAE
Gain = (S.P.) - (C.P.)
Loss = (C.P.) - (S.P.
)Loss or gain is always reckoned on C.P.
Gain Percentage: (Gain %) 
   Gain % =Gain x 100C.P.
Loss Percentage: (Loss %)   
Loss % =Loss x 100C.P.
Selling Price: (S.P.) 
  SP =(100 + Gain %)x C.P100
Selling Price: (S.P.)    SP =(100 - Loss %)x C.P.100
Cost Price: (C.P.)   
C.P. =100x S.P.(100 + Gain %)
Cost Price: (C.P.)   
 C.P. =100x S.P.(100 - Loss %)\
