    Step-by-step explanation:

    Let the total money spent be x

    Therefore average spending is x/9

    Average of 8 persons is ₹12

    Total spent by 8 persons is 12*8= ₹96

    Therefore, Money spent by ninth is x-96

    Given that

    x - 96=  \frac{x}{9}  + 8 \\ 9x - 864 = x + 72 \\ 8x = 936 \\ x =  \frac{936}{8}  = 117
