Well,
I came across this question while practicing DS.(Source:knewton).Feel it is good one so posting it here.
In 2001, Rembolse Insurance sold 8,250 travel insurance policies in its international division. If 255 of the international division's policies resulted in a claim, what was the claim rate, i.e. the number of claims per 100 policies, for the domestic division in 2001?
1. In 2001, the overall claim rate for the international and domestic divisions combined was 4.5 claims per 100 policies.
2. In 2001, the domestic division sold 4,550 policies.
[A] Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
[C] BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
[D] EACH statement ALONE is sufficient.
[E] Statements (1) and (2) TOGETHER are NOT sufficient.
My way of solving it
Sample A total=8250 value=225
Sample B total=x value=y (y/x)x100
Total A+B total=8250+x value=225+y ((225+y)/(8250+x) * 100)
Question is
(y/x)*100=?
St 1
1. In 2001, the overall claim rate for the international and domestic divisions combined was 4.5 claims per 100 policies.
((225+y)/(8250+x) * 100) =4.5
dont feel it is sufficient
St 2
2. In 2001, the domestic division sold 4,550 policies
X=4550
No way to get Y so insufficent
1+2 seems to be sufficent
when we put value of x from st 2 in eq from st 1 we get y hence y/x * 100
I think its C
I think its like if speed from A-B is 9km/h and B-C is 6km/hr speed for A-C is not 9+6/2
same with percent here i guess
Dont know OA.
The only confusion is if A alone is sufficient or not.If above 'speed' mechanism doesnt apply then answer will be A.But i feel that speed principle even applies in this case so should be C
What do you think?
