  1. Step-by-step explanation:

    Let number of Rs5 coins be x

    Number of Rs 2 coins =3× Number of 5 Rs coins =3x

    Number of Re1 coins =160−(x+3x)

    =160−4x

    Amount of Rs5 coins =5×x=5x

    Amount of Rs2 coins =2×3x=Rs6x

    Amount of Re1 coins =(160−4×x)

    =160−4x

    As per the question, Total amount =Rs300

    160−4x+5x+6x=300

    7x=300−160

    x=

    7

    140

    x=20

    Number of Re 1 coins =160−4x

    =160−4×20

    =80

    Number of Rs2 coins =3x=3×20=60

    Number of Rs5 coins =x=20
