1) The number of Chipmunks fans among the spectators is 20% greater than the number of Bullfrogs fans.
2) The total number of spectators at the baseball game is 4000.
The OA is A
Source: Princeton Review
Say there are B no. of Bullfrog fans and C no. of Chipmunk fans. We have to get the value of B : C.
Let's take each statement one by one.
1) The number of Chipmunks fans among the spectators is 20% greater than the number of Bullfrogs fans.
C = 120% of B => C = 6B/5 => B/C = 5/6. Sufficient.
2) The total number of spectators at the baseball game is 4,000.
B + C = 4,000. However, we can't get the value of B : C. Insufficient.
Though we answered the question correctly, the figure 4,000 in Statement 2 is inconsistent with the information given in Statement 1. The total no. of spectators must be a multiple of 11. We see that 4,000 is not a multiple of 11.
Let's get this.
From Statement 1, we have C = 6B/5. Thus, B + C = B + 6B/5 = 11B/5
Equating 11B/5 to 4,000, we get B = 20,000/11 = not an integer. Since no. of fans is an integer, the total no. of spectators must not be 4,000.
In a DS question, the question narration, Statement 1 and Statement 2, together make a holistic situation.
The correct answer:
A
Hope this helps!
