Data Sufficiency

I dont remember the exact question and the one that am posting here is just a paraphrased version . However , the modified version is also similar to the original question .

Mrs.T's students are awarded bonus points for every question they answer correct . Bonus points = two times the ten's digit of the base score which is numbered from 10-99 . If Mrs.T's student answers one question correctly , is the bonus point awarded to the base score greater than 17% ?

a. The base score is numbered from 50 - 99.
b. Mrs.T awarded a total of 16 bonus points to the student .

we set question "is the bonus point awarded to the base score greater than 17%" 17% of the base score is meant; the scores numbered from 10 to 99 - for each one correct score two times the ten's digit of the base score is awarded in bonus points, and we know that Mrs.T's student answers correctly one question.

st(1) 1 correct answer, the base score lies within {50...90}, the bonus points can not be assigned Not Sufficient.
st(2) 16 bonus points should mean the base score starts with the digit '8'. So base score = 8X where X is any digit from 0 to 9; 16/8X > 0.17 the answer - Yes, Sufficient

Hi Night reader. Agree with ur STatement 2.

But In statement 1, 1 correct answer & the base score lies within (50...90), So:

If we take base no as 55 say then: tens Digit=5 ; Bonus pt =5*2=10. Now 10/55=18.18%. Bur for say we take 59. Tens digit=5. Bonus=5*2=10. Now 10/59=16.94. < or equal to 17(approx). But the question asks us : Is the bonus point awarded to the base score greater than 17% ? Clearly we dont have a clear answer & therefore 1st statement is insufficient.'

Ur statement :st(1) 1 correct answer, the base score lies within {50...90}, the bonus points can not be assigned :

Did not get this. Why cant u assign the bonus pts.

Am i missing sumthing. Pls clarify

@ankur.agrawal: to assign the bonus points we need to know the first digit of the base score; the base score is not defined in st(1) it lies within {50-99} interval. If bases score is 59 then the bonus points are 10 which is less than 17%; if the base score is 99 then the bonus points are 18 which is greater than 18%.

hope this helps.
