[ Chapter 1] Profit and Loss (Math Notes)
Selling Price:( विक्रय मूल्य )
The price, at which an article is sold, is called its selling prices, abbreviated as S.P.
(जिस मुल्य पर कोई वस्तु बेची जाती हैं )
Cost Price:( क्रय मूल्य)
The price, at which an article is purchased, is called its cost price, abbreviated as C.P.
(जिस मुल्य पर कोई वस्तु खरीदी जाती है )
Loss:(हानि )
If S.P. is less than C.P., the seller is said to have incurred a loss.
(अगर विक्रय मुल्य क्रय मुल्य से कम है)
Profit or Gain:(लाभ )
If S.P. is greater than C.P., the seller is said to have a profit or gain.
(अगर विक्रय मुल्य क्रय मुल्य से जादा है)
Loss or gain is always reckoned on C.P.
Gain = (S.P.) - (C.P.)
Loss = (C.P.) - (S.P.)
Important Formula
Gain Percentage: (Gain %)
( लाभ) Gain %= (Gain × 100 / C.P.)
( हानि ) Loss %= (Loss × 100 / C.P.)
यदि कोई दुकानदार अपनी वस्तु क्रय मुल्य पर बेचता है पर त्रुटि बाट का उपयोग करते हैं तब लाभ =
अगर कोई व्यक्ति कोई वस्तु x% लाभ x% हानि पर बेचता है तो हमेसा उसे हानि होती है
Selling Price:( विक्रय मूल्य )
The price, at which an article is sold, is called its selling prices, abbreviated as S.P.
(जिस मुल्य पर कोई वस्तु बेची जाती हैं )
Cost Price:( क्रय मूल्य)
The price, at which an article is purchased, is called its cost price, abbreviated as C.P.
(जिस मुल्य पर कोई वस्तु खरीदी जाती है )
Loss:(हानि )
If S.P. is less than C.P., the seller is said to have incurred a loss.
(अगर विक्रय मुल्य क्रय मुल्य से कम है)
Profit or Gain:(लाभ )
If S.P. is greater than C.P., the seller is said to have a profit or gain.
(अगर विक्रय मुल्य क्रय मुल्य से जादा है)
Loss or gain is always reckoned on C.P.
Gain = (S.P.) - (C.P.)
Loss = (C.P.) - (S.P.)
Important Formula
Gain Percentage: (Gain %)
( लाभ) Gain %= (Gain × 100 / C.P.)
( हानि ) Loss %= (Loss × 100 / C.P.)
- (विक्रय मुल्य ) Selling Price: (S.P.)
SP = 
(100 + Gain %) x C.P 
100 - (विक्रय मुल्य ) Selling Price: (S.P.)
SP = (100 - Loss %) x C.P. 100 - (क्रय मुल्य ) Cost Price: (C.P.)
C.P. = 100 x S.P. (100 + Gain %) - (क्रय मुल्य ) Cost Price: (C.P.)
C.P. = 100 x S.P. (100 - Loss %)
5. If a trader professes to sell his goods at cost price, but uses false weights, then
| Gain % = | | Error | x 100 | %. |
| (True Value) - (Error) |
6. If an article is sold at a gain of say 35%, then S.P. = 135% of C.P.
अगर कोई वस्तु 35% लाभ पर बेची जाती हैं
7. If an article is sold at a loss of say, 35% then S.P. = 65% of C.P.
अगर कोई वस्तु 35 % हानि पर बेची जाती हैं तब S. P. =65% OF S. P.
8 . When a person sells two similar items, one at a gain of say x%, and the other at a loss of x%, then the seller always incurs a loss given by:
| Loss % = |  | Common Loss and Gain % |  | 2 | = | . | ||||
| 10 |
9. If selling price is ₹X and profit is 20% then cost price = ₹(100/120) *X
अगर विक्रय मुल्य ₹X और लाभ 20% है तो क्रय मुल्य =
10. If selling price is ₹X and loss is 20% then cost price = ₹ (100/80) ×X
अगर विक्रय मुल्य ₹X और हानि 20% है तो क्रय मुल्य =
