When a player in a certain game tossed a coin a number of times, 4 more heads than tails resulted. Heads or tails resulted each time the player tossed the coin. How many times did heads result?

Given: H-4=T.
Question: T=?

(1) The player tossed the coin 24 times. H+(H-4)=24. We can find H. Sufficient.

(2) The player received 3 points each time heads resulted and 1 point each time tails resulted, for a total of 52 points. 3H+1*(H-4)=52. The same here: we can find H. Sufficient.

Answer: D.

We are given that (T + 4) + T = Total tosses, by the stem


1) Gives us total tosses, so now we only have one unknown and thus we can solve for heads

2) (I incorrectly answered that this is insufficient), this one is pretty straightforward: The stem tells us that 4 more heads than tails resulted.. Now we're told that for each tails, he gets 1 point.. So just subtract 4 points from 52, and now we know how many points stem from heads, which is 48. Divide 48/3 and now you have number of heads. Sufficient.


So, D.
