(iv) SP = 34.40 and gain = 15/2%
(iii) SP = 657.60 and loss = 4%


Plz answer I will mark best answer as brainliest

Answer 1

Answer:

Step-by-step explanation:

1. sp= 1596

     gain % = 12%

     cp = [100/(100+gain%) × sp]

     so, cp = (100/112 × 1596)

     = 1425

    2  Formula :cp = 100/100 - loss% × sp

      Cp=100/100 - 13/2 × 2431

      = 100/100 - 6.5 × 2431

     = 100/93.5 × 2431

    = 100/1 × 26

     = 2600

   

   3  C. P. = 100 x S. P.

      100-loss%

     so, c. p. = 100 x S. p.

     100-4

     = 100 x 657.60

      96

      = 25 x 675.60

     24

     = 25 x 27.4

     = 685

     so the c. p. is (685 )........
