Question

Kisi Vastu ko 24 rupay mein bechane Par utna Hi pratishat Labh hota hai Jitna Vastu ka cray mulya hai Vastu Ka Kray mulya gyat kijiye​

Answer 1

Answer:

Rs 20

Step-by-step explanation:

Vastu Ka Kray mulya  = C  Rs

(Cost Price of C )  = Rs C

24 rupay mein becha

Selling  Price = Rs 24

pratishat Labh = Kray mulya

% Profit  = Cost Price = C

pratishat Labh (Profit %)   =   (( 24 - C)/C)  * 100

 (( 24 - C)/C)  * 100   = C

=> 2400 - 100C = C²

=> C² + 100C - 2400 = 0

=> C² + 120C - 20C - 2400 = 0

=> C(C + 120) -20(C + 120) = 0

=> (C - 20)(C + 120) = 0

=> C = 20

Vastu Ka Kray mulya = Cost Price = Rs 20

Answer 2

Answer:

c.p = 10×√25+s.p - 50

c.p = 10×√25+24 -50

c p= 10×√49-50

c.p =10×7-50

c.p=70-50

c.p= 20answer

rule hai when c.p=profile%/loss%

(c.p= 10×√25+/-s.p -50)

+ for profit and

-for loss
