2 roman - iii, iv
​

Answer 1

Answer:

Step-by-step explanation:

1) (iii) CP = Rs. 345 and SP = Rs 372.60. Since SP > CP, it will be gain.

   The formula to calculate Gain% = 100* [SP - CP /CP]

                                                     = 100 *[372.60 - 345 / 345]

                                                     =   27.8/345 * 100

                                                     = 8%.

   (iv) CP = Rs. 80, SP = Rs. 76.80. Since SP < CP, it will be Loss.

     The formula to calculate Loss% = 100* [CP - SP /CP]

                                                     = 100 *[80 - 76.80 / 80]

                                                     =   3.2/80 * 100

                                                     = 4%.

2) (iii) CP = Rs. 875 Loss% = 12%

    The formula to calculate Loss% = 100* [CP - SP /CP]

           12   = 100 * [875 - SP/875]

           => 12 * 875 /100 = 875 - SP

           =>  105 = 875 - SP

           => SP = 875 - 105 = Rs. 770

(iv) CP = Rs. 645 Loss% = 13 1/3% = 40/3%

    The formula to calculate Loss% = 100* [CP - SP /CP]

           40/3   = 100 * [645 - SP/645]

           => 40/3 * 645 /100 = 645 - SP

           =>  86 = 645 - SP

           => SP = 645 - 86 = Rs. 559.
