**Data Sufficiency Questions for SBI PO 2017 Answers**

**1. **(b) From A —>m + n = 10 × k (let k is an integer value)

From B —> 10m + 7n = 70 × 1 (Let l is an integer value)

From C —> n > m

From A and B

3n = 100k – 70l

3n = 10(10k – 71) : Hence n is divisible by 10. Thus option A and B together are needed to solve the question.

**2.** (a) Area of quadrilateral BFDE = Area of rectangle ABCD – Area of AABE – Area of ADCF

= 120 – 30 – 25 = 65

**3. **(a)

Ratio of Investment of A, B and C

(3000 × 4 + 1800 × 5 + 3600 × 3)

: (4000 × 4 + 8000 × 5)

: (14000 + 33600)

31800 : 56000 : 47600

159 : 280 : 238

Profit of C

=238000

Average of profit earned by (A + B + C) = 225666

**4. **(b) We can get ratio of investment from either statement B alone or C alone so profit of B can be determined from option b

**5. **(d) From A and C we can determine the value ratio of efficiency between men, women and children from A & B we can also determine the value of ratio of men, women and children. We can calculate the answer from B and C.

**6. **(c)

From A : Profit = 20% and

S.P. = 3828.

From C : (x + y) – (x – y) = 28

y = 14

Andx + y= 90 (From B)

x = 76

∴ A alone or B and C together are sufficient.

**7. **(b) Here, For quantity I ➝

First the different no. of ways to arrange 5 men or 5 women = 5!

Now,

_M_M_M_M_M

No. of ways of arranging 5 men and 5 women such that no two women or men sit together = 2 × 5! × 5!

For quantity II ➝

No. of ways of arranging 5 men and 5 women such that all men sit together ➝ 6! × 5!

∵ 2 × 5! × 5! × 6! × 5!

So, Quantity I < Quantity II

**8. **(b) For quantity I ➝

Since S is an acute angle means < 90°

∴ (a + 40) + a < 90

(2a+40) < 90

2a <50

a < 25°

For quantity II ➝ 25°

∴ Quantity I < Quantity II

**9. **(a)

For Quantity I ➝

Let required no. = 10x + y

∴ 10y + x = 10x + y +36

9y – 9x = 36 y – x = 4

∴ unit digit of the no. should be 4 more than the ten’s digit of the number.

∴ such possible numbers from 1 to 63 are = 04, 15, 26, 37, 48, 59

∴ Required probability

For quantity II ➝

Possible numbers from 1 to 63 = 8, 24, 40, 56

Required probability

∴ Quantity I > Quantity II

### Data Sufficiency Questions for SBI PO 2015 Exam

**Each of the questions below consists of a question and two statements numbered I and II give below it. You have to decide whether the data provided in the statements are sufficient to answer the question. Read the question and both the statements and –**

Give answer (a) if the data in statement I alone are sufficient to answer the question, while the data in statement II alone are not sufficient to answer the question.

Give answer (b) if the data in statement II alone are sufficient to answer the question, while the data in statement I alone are not sufficient to answer the question.

Give answer (c) if the data either in statement I alone or in statement II alone are sufficient to answer the question.

Give answer (d) if the data even in both the statements I and II together are not sufficient to answer the question.

Give answer (e) if the data in both the statements I and II together are necessary to answer the question. **(SBI PO Main 2015)**

**1. **Train ‘A’ running at a certain speed crosses another train ‘B’ running at a certain speed in the opposite direction in 12 seconds. What is the length of train ‘B’?

(I). The length of both the trains together is 450 metres.

(II). Train ‘A’ is slower than train ‘B’.

**2. **Area of a rectangle is equal to the area of a right angled triangle. What is the length of the rectangle ?

(I). The base of the triangle is 40 cms.

(II). The height of the triangle is 50 cms.

**3. **What was the total compound interest on a sum after three years ?

(I). The interest after one year was 100/- and the sum was 1,000/-.

(II). The difference between simple and compound interest on a sum of 1,000/- at the end of two years was 10/-.

**4.** What is the two digit number where the digit at the unit place is smaller ?

(I). The difference between the two digits is 5.

(II). The sum of the two digits is 7.

**5. **What is the speed of the boat in still water ?

(I). It takes 2 hours to cover distance between A and B downstream.

(II). It takes 4 hours to cover distance between A and B upstreams.

**Data Sufficiency Questions for SBI PO 2015 Answers**

**1.** (d) Let S_{1} and S_{2} be the speed of train A and B respectively

Time taken by both the trains in crossing each other.

S_{1} and S_{2} can have so many values. Both statement I and II are not sufficient to find speed of train B.

**2. **(d) Area of rectangle = Area of triangle.

From the information given in both the statements, we can find area of triangle or area of rectangle. For finding length, breadth is required, which is not known.

**3. **(c) From the statement I.

Thus we have,

P = ₹ 1000, r = 10%, t = 3 years

Hence, C.I. can be determined

From the statement II.

∴ C.I – S.I

⇒ 2000r + r^{2} – 200r = 100

⇒ r = 10

**4. **(d)

∴ Number = 10y + x

From statement I,

y – x = 5 —— (i)

From statement II,

y + x = 7 —— (ii)

From (i) and (ii), x, y can be calculated and two digit number can be found.

**5. **(d) Let the distance between A and B be z km.

Again, let speed of boat in still water be x kmph and that of stream be y kmph.

∴ Rate downstream = (x +y) kmph

Rate upstream = (x – y) kmph

From statement I,

—— (i)

From statement II,

—— (ii)

we have two equations and three variables, therefore both equations are not sufficient.

**3. **(d) Using statement II and III, we can find the number of students in second class and pass class only. As there is no link given between the first class and the other classes, we cannot find the number of students in first class.

**4. **(e) Using Statement I :

Using Statement II :

A is 40% of total. So B is 60% of total amount invested.

Using statement III:

A = 45000
