SNAP Data Sufficiency Questions
Question 1
What is the speed of boat in still water?
I. The boat covers 12 km in 2 hours in downstream.
II. The boat covers same distance in 4 hours in upstream.
III. The speed of stream is one third of that of boat in still water.
Solution
Downstream = boat + stream = $$\frac{12}{2}$$ + stream = 6 km/hr
Upstream =boat - stream = $$\frac{12}{4}$$ - stream = 3 km/hr
Solving the above equations we get boat = 4.5 km/hr and stream = 6 - 4.5 = 1.5
Speed of the stream = $$\frac{1}{3}$$rd of that of the boat in still river = 1.5
Question 1
Four classes Rural Marketing, Digital Marketing, International Marketing and Service Marketing were taught in four consecutive periods of one hour each starting from 8.00 am on a week day.
Read the statements and find out the probable option which can be sufficient to answer the question:
At what time was the Digital Marketing class scheduled?
Statement I. International marketing class ended at 10.00 am which was preceded by Service Marketing.
Statement II. Rural Marketing was scheduled as the last class.
Statement III. International Marketing was immediately followed by Digital Marketing.
Solution
Four classes Rural Marketing, Digital Marketing, International Marketing and Service Marketing were taught in four consecutive periods of one hour each starting from 8.00 am on a week day.
Digital Marketing class was scheduled:
Statement I. International marketing class ended at 10.00 am which was preceded by Service Marketing.
We can make the following schedule
8.00 am- 9.00 am: Service Marketing
9.00 am- 10.00 am: International Marketing
10.00 am- 11.00 am: ____________
11.00 am- 12.00 noon: ____________
Statement II. Rural Marketing was scheduled as the last class.
Statement III. International Marketing was immediately followed by Digital Marketing.
We can subsequently find the exact time when Digital Marketing is scheduled from both the statements.
Hence the correct answer is Option C
Question 2
Read the statements and find out the probable option which can be sufficient to answer the question:
What is the total monthly salary of Kakade?
Statement I. Kakade‘s basic salary is Rs.100/- more than Madan’s salary, who also serves in Kakade’s company.
Statement II. Other allowance taken by Madan besides his basic salary is $$\frac{1}{10^{th}}$$ of Kakade’s salary.
Statement III. Madan’s basic salary is Rs.15000/- per month.
Solution
Statement I. Kakade‘s basic salary is Rs.100/- more than Madan’s salary, who also serves in Kakade’s company.
Statement II. Other allowance taken by Madan besides his basic salary is 1/10th of Kakade’s salary.
Statement III. Madan’s basic salary is Rs.15000/- per month.
From all the three statements we can find the basic monthly salary of Kakade but we cannot calculate the allowance he gets, thus the data is insufficient.
Question 3
Babu is younger than Gopu. Somu is older than Pappu. Read the statements and find out the probable option which can be sufficient to answer the question:
Who among them is the oldest?
Statement I. Somu is older than Babu.
Statement II. Gopu is older than Somu.
Statement III. Pappu is the youngest of all.
Solution
Babu is younger than Gopu. Somu is older than Pappu. Babu < Gopu & Pappu < Somu
Statement I. Somu is older than Babu. ....Gopu can still be older than Somu, so we cannot find the oldest among all.
Statement II. Gopu is older than Somu. Here Gopu will definitely be the oldest
Statement III. Pappu is the youngest of all. Cannot find the oldest among all.
Hence Option D is correct.
Each question consists of a statement and/or a question followed by two statements I and II. Identify an option which provides sufficient data to answer the given question. Mark your answer as
A. if the data in statement I is sufficient and II is not required;
B. if the data in statement II is sufficient and I is not required;
C. if the data in both statements is necessary;
D. if the data in both statements is not sufficient to answer the question.
Question 1
The total of the present ages of A, B, C and D is 96 years. What is B's present age?
I. The average age of A, B and D is 20 years.
II. The average age of C and D is 25 years.
Solution
It is given that A+B+C+D = 96
Using statement I alone A+B+D = 20*3 = 60
Thus we can say that C = 96-60 = 36
Using Statement II alone
C+D = 2*25 = 50 and hence A+B = 46
Using both statements I and II
A+B = 46 hence D = 14
We still can't find the value of B even after using both the statements
Each question consists of a statement and/or a question followed by two statements I and II. Identify an option which provides sufficient data to answer the given question. Mark your answer as
A. if the data in statement I is sufficient and II is not required;
B. if the data in statement II is sufficient and I is not required;
C. if the data in both statements is necessary;
D. if the data in both statements is not sufficient to answer the question.
Question 2
Deepak's marks in Hindi are 15 more than the average marks obtained by him in Hindi, Economics, Sociology and Philosophy. What are his marks in Philosophy?
I. The total marks obtained by him in Hindi and Philosophy together is 12.
II. The difference between the marks obtained by him in Sociology and Economics is 120.
Solution
Let h,e,s and p represent the scores in Hindi, Economics, Sociology and Philosophy respectively.
$$h\ =\ 15+\ \frac{\ h+e+s+p}{4}$$
From statement I alone we can see that even though we know h+p = 12 we can't determine exact value of h
In statement II we see that s-e = 120. Even if we input this in the original equation, we won't be able to determine the exact value of h.
Using both statement together also does not give the definite value of h
Each question consists of a statement and/or a question followed by two statements I and II. Identify an option which provides sufficient data to answer the given question. Mark your answer as
A. if the data in statement I is sufficient and II is not required;
B. if the data in statement II is sufficient and I is not required;
C. if the data in both statements is necessary;
D. if the data in both statements is not sufficient to answer the question.
Question 3
What was the cost price of the suitcase purchased by Richard?
I. Richard got 20% concession on the labeled price.
II. Richard sold the suitcase for Rs 2000 with 25% profit on the labeled price.
Solution
Here we have to find the CP of a suitcase for Richard and M represent the labeled price
From Option I we see that he got discount of 20%on Marked Price. But since we do not know the MP it is not possible to determine CP for Richard
Using only Option II we see that we can we can obtain the profit in terms of marked price but not the cost price.
When we use the option I and II together we can determine CP and Profit in term of M and thus know the CP for Richard
Each question consists of a statement and/or a question followed by two statements I and II. Identify an option which provides sufficient data to answer the given question. Mark your answer as
A. if the data in statement I is sufficient and II is not required;
B. if the data in statement II is sufficient and I is not required;
C. if the data in both statements is necessary;
D. if the data in both statements is not sufficient to answer the question.
Question 4
B alone can complete a work in 12 days. How many days will A, B and C together takes to complete the work?
I. A and B together can complete the work in 3 days.
II. B and C together can complete the work in 6 days.
Solution
Assume total work to be done = 12 units. Then $$\eta_B$$ = 1 unit/day
Using only statement I, we get $$\eta_A$$+ $$\eta_B$$ = 12/3 = 4unit/day.
Thus only $$\eta_A$$ can be calculated.
Similarly using statement II, we can calculate $$\eta_C$$ only.
Using both the statement together will give $$\eta_A$$ as well as $$\eta_C$$ and thus we will get the required answer. Hence option C is correct
