Answer:
72 is the answer.
Step-by-step explanation:
Let the no. of cards Mike start with be x.
So,next he added 8 more cards.
which implies that cards he have in present=x+8
Next dog ate half.
which means no. of cards he have now=1/2(x+8)
it is given that no. of cards with him=40
ATQ,
1/2(x+8)=40
x+8=40×2
x+8=80
x=80-8
x=72
Therefore,no. of cards Mike start with is 72.
