    Answer:

    Step-by-step explanation:

    Take x=number of RS 1 coin

    y=number of 50p coin

    She has total 70 coins so

    x+y=70-i)

    She has total 45rs so

    x + 0.5y=45-ii)

    Subtracting i) and ii)

    Then we get

    0.5y=25

    y=25÷0.5

    y=50

    Means there were 50 coins of 50paisa.

    Now putting value of y in i)

    So we will get x=20

    So it means that there were 20 coins of 1rs coin

    So 1rs coins=20

    50p coins=50
