# Data Sufficiency Practice set 4

Directions (1-10): Each of the question below consists of a question and two statements numbered I and II given below it. You have to decide whether the data provided in the statements are sufficient t answer the question.

1) What is Sunita`s rank form the top in the class of 40students?

(i) Rani is 4 ranks below Sunita and isthirty first from the bottom.

(ii) Amit is two ranks above Sunita and is thirty seventh from the bottom.

a) If the data in statements I alone are sufficient to answer the question, while the data in statement II alone are not sufficient to answer the question.

b) If the data in statements II alone are sufficient to answer the question, while the data in statement I alone are not sufficient to answer the question.

c) If the data in statements I alone or in statement II alone are sufficient to answer the question.

d) If the data in both the statement I and II are not sufficient to answer the question.

e) If the data in both the statements I and II together are necessary to answer the question.

1.(c)

From statement I

Rank of Rani from the top = 40  – 31 + 1 = 10

Therefore, rank of Sunita = 10 – 4 = 6th

From statement II

Rank of Amit from the top = 40 – 37 + 1 = 4th

Therefore, rank of Sunita = 4 +2 = 6th

2)What is the code for `Comfort` in the code language?

Or, ? = 9 × 7 + 9

Or, ? = 63 + 9 = 72

From statement II

16 \$ 4 * 2 # 2 = 10

OR, 16 ÷ 4 × 2 + 2 = 10
