Data Sufficiency Question 71
Directions : Each of the questions given 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 is sufficient to answer the question. Read both the statements. (IBPS SO (Agriculture) Exam, 29.01.2017)
Give answer (1) if the data in statement I alone is sufficient to answer the question, while the data in statement II alone is not sufficient to answer the question.
Give answer (2) if the data in statement II alone is sufficient to answer the question, while the data in statement I alone is not sufficient to answer the question.
Give answer (3) if the data in statement I alone or in statement II alone is sufficient to answer the question.
Give answer (4) if the data in both the statements I and II is not sufficient to answer the question.
Give answer (5) if the data in both the statements I and II together is necessary to answer the question.
- What distance (in $km$ ) the boat can travel downstream in 20 minutes?
I. The distance travelled by the boat upstream in 48 minutes is equal to the distance travelled by the boat downstream in 36 minutes.
II. The respective ratio between speed of the boat in still water and speed of the water current is $7: 1$.
Show Answer
Correct Answer: 71. (4)
Solution: 71. (4) From both statements, Speed of boat in still water $=7 x \mathrm{~m} . / \mathrm{min}$.
Speed of water current
$=x \mathrm{~m} . / \mathrm{min}$.
$\therefore$ Rate downstream
$=8 x \mathrm{~m} . / \mathrm{min}$.
Rate upstream $=(7 x-x) \mathrm{m} . / \mathrm{min}$. $=6 x \mathrm{~m} / \mathrm{min}$.
$\therefore 6 x \times 48=8 x \times 36$
No result.
