    LET NUMBER OF TWO RUPEES COIN BE ‘X’

    LET THE NUMBER OF 5 RUPEES COIN BE ‘Y’

    1ST EQUATION:-

                           X+Y=30

    2ND EQUATION:-

                         2X+5Y=114

    BY SUBSTITUTION METHOD:-

               LET WE TAKE EQUATION 1 (X+Y=30) SO,X=30-Y

    NOW LET WE SUBSTITUTE VAL OF X IN EQUATION 2

        2(30-Y)+5Y=114

    60-2Y+5Y=114

    3Y=54

    Y=54/3

    Y=18

    LET WE SUBSTITUTE VALUE OF Y IN EQUATION 1

    X+18=30

    X=30-18

    X=12

    THE TOTAL NUMBER OF 2 RUPEE COIN IS 12

    TOTAL NUMBER OF 5 RUPEE COIN IS 18

    THE VALUE OF 2 RUPEE COIN IS 12×2=24

    THE VALUE OF 5 RUPEE COIN IS 18×5=90
