plz ans it briefly ​

Answer 1

Answer:

s.p of 1st item = RS.18,602

Gain = 31%

C.P. = S.p*100/100+Gain%

       = 18602*100/100+31

        = 1860200/131

        = Rs.14200

s.p of 2nd item = RS.18,602

Loss = 29%

C.P. = S.p*100/100-Loss%

       = 18602*100/100-29

       = 1860200/71

       = Rs.26200

Cp of both items =14200 +26200

                            = Rs.40400

Sp of both items = 18,602 + 18,602

                            = Rs.37204

here, C.P.> S.P. so , it is a loss.

Loss = 40400-37204

        = Rs,3196

Loss % = Loss/C.P*100

            = 3196/40400*100

            = 7.91%
