The rules of a certain board game specify that for each turn, a player will receive either 60 points or 10 points. If a player takes 20 turns, how many points did he receive?
(1) If the player had received 60 points in one more turn than he did, his total would be 50 points higher.
(2) If the player had received 60 points in four more turns than he did, his total would be 200 points higher.
Let x be the number of turns in which the player receives 60 points and y be the number of turns in which the player receives 10 points. Thus, total number of turns = x+y, and total number of points = 60x+10y
Now, let's look at each statement individually and then at both of them together (if required):
Statement 1: If the player had received 60 points in one more turn than he did, his total would be 50 points higher.
As per this statement:
60(x+1) + 10(y-1) = 50 + 60x + 10y
Thus, 60x + 60 + 10y - 10 = 50 + 60x + 10y
We get => 50 = 50 (as we can cancel off the remaining terms)
Hence, this statement alone is insufficient.
Now, let's take a look at Statement 2 closely:
Statement 2: If the player had received 60 points in four more turns than he did, his total would be 200 points higher.
As per this statement:
60(x+4) + 10(y-4) = 60x + 10y + 200
60x + 240 + 10y - 40 = 60x + 10y + 200
We get => 200 = 200 (as we can cancel off the remaining terms)
Hence, this statement alone is insufficient as well.
Since both the statements have LHS = RHS and do not provide information that would help us determine the number of points received, the correct answer is
Option E - Neither statement alone nor together is sufficient.Hope this helps!
