Answer 1

Answer:

HE MAKE THE PROFIT OF RS 2000

Step-by-step explanation:

CP OF 1ST MACHINE =X

CP OF 2ND MACHINE=20000-X

PROFIT =10 %

SP=110X/100

THEN, LOSS =10%

SP =22000-110X

NOW, SP OF 1ST MACHINE =SP OF 2ND MACHINE

          110X/100= 22000-110X

         220X= 2200000

        X= 2200000/220

      X =10000

AND, CP OF 1ST MACHINE = RS 10000

         CP OF 2ND MACHINE =RS 20000-10000

                                                  = 10000

NOW SP =110X10000/100= 11000

       SP OF 2ND MACHINE =22000-11000

                                             11000

AGAIN TOTAL CP =RS 20000

          TOTAL SP =22000

SO PROFIT = SP -CP

                  22000-20000

              2000
