**Hello Aspirants.** Welcome to Online Quantitative Aptitude section in AffairsCloud.com. Here we are creating question sample From **DATA SUFFICIENCY** topic, which is common for all the IBPS,SBI exam RBI,,SSC and other competitive exams. We have included Some questions that are repeatedly asked in exams !!!

**Bank PO Level Questions** :-

**Q(1 – 5) Each of the questions 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 to answer the question. Read all the three statements and give answer: –**

**A. **If the data in statement I alone is sufficient to answer the question.

**B.** If the data in statement II alone is sufficient to answer the question.

**C. **If the data either in statement I alone or statement II alone are sufficient to answer the question.

**D. **If the data given in both I and II together 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.

**What is the speed of the train whose length is 210m?**

I. The train crosses another train of 300m length running in opposite direction in 10s

II. The train crosses another train running in the same direction at the speed of 60kmph in 30s.

Answer –**E. if****the data in both the statements I and II together are necessary to answer the question**

**Explanation :**

L1 = 210m(Given)

From Statement I, L2 = 300m

L1 + L2 = 210m +300m =510m

S1 + S2 = [D/T] = 510/10 = 51m/s

From Statement II,

S2 = 60kmph = 60*(5/18) = 50/3 m/s

S1 – S2 = 510/30 = 51/3 => S1-50/3 = 51/3

S1 = 101/3 m/s

Thus both the statements are required to answer the question.**What is the man’s speed in still water?**

I. The speed of the stream is one-third of the man’s speed in still water.

II. In a given time, the man can swim twice as far with the stream as he can against it.

Answer –**D. If the data given in both I and II together are not sufficient to answer the question.**

**Explanation :**

From Statement I, Speed of stream = 1/3 * Man’s speed = Man’s speed = 3* Speed of stream

From Statement II, Man’s speed = 2* Speed of stream

Thus both the statements are not sufficient to answer the question.**What is the Ratio of male to female officers in the police force in town T?**

I. The number of female officers is 250 less than half the number of male officers.

II. The number of female officers is 1/7 the number of male officers.

Answer –**B. If the data in statement II alone is sufficient to answer the question.**

**Explanation :**

From Statement I,

Number of male officers = x

Number of female officers = x/2 – 250

Ratio can’t be calculated from Statement I.

From Statement II,

Number of male officers = x

Number of female officers = x* 1/7

Ratio = x/(x/7) = 7:1

Thus Statement II alone is sufficient to answer the question.**What is the rate of the Compound Interest?**

I. A certain amount invested at the compound interest rate amounts to Rs. 1331

II. The amount was invested for a period of three years.

Answer –**D. If the data given in both I and II together are not sufficient to answer the question.**

**Explanation :**

Principal is not given, We can not find the rate of CI from both statements.**What is the difference between the two digits in a two-digit number?**

I. The sum of the two digits is 8.

II. 1/5 of that number is 15 less than 1/2 of 44

Answer –**B. If the data in statement II alone is sufficient to answer the question.**

**Explanation :**

Statement I not sufficient

From statement II,

1/5 * x = 1/2 *44 -15

x = 35, Difference between the two digits is = 2**A, B, and C together start a business with a total investment of 15000. At the end of the year, the total profit is Rs.3000. What is A’s share in the profit?**

I. A’s contribution is 3/2 times of B’s

II. B’s contribution is twice that of C.

III. A’s contribution is thrice that of C.

A. I and II

B. II and III

C. All I, II and III

D. Any two of the three

E. None of the Above

Answer –**D. Any two of the three**

**Explanation :**

C = x

From I and II

C = x, B = 2x, A = (3/2 * 2x) => A = 3x

From II and III

C = x, B = 2x, A = 3x

From I and III

C = x, A = 3x, B = (2/3 * 3x) => B = 2x

A:B:C = 3:2:1, A’s share = (3000 * (3/6)) = 1500

Thus any two of the three statements, are sufficient to answer the question.**What is the monthly income of Mr. X?**

I. Mr. X spends 85% of his income on various items and remaining amount is saved

II. Monthly savings of Mr. X are 4500

III. Out of the total money spent by Mr.X in a month, one-fifth is spent on food and remaining amount of Rs.20400 on other items.

A. Only II

B. Only III

C. All the given statements are Insufficient

D. Only either II or III

E. None of the Above

Answer –**E. None of the Above**

**Explanation :**

Let the income of Mr.X = y

From I and II

15% of y = 4500 => y = 30000

From II and III

4/5th of expenditure = 20400 => Expenditure = Rs. 25500, Savings = Rs.4500

Income = 25500 + 4500 = 30000

From I and III

4/5 of 85% of x = 20400

x = 30000

Thus any two of the three statements, are sufficient to answer the question. Ans option – None of the Above**What is the present age of Rahul?**

I. The present age of Rahul is half of his father’s age

II. After 5 years, the ratio of ages of Rahul and his father is 6:11

A. I and II

B. I and III

C. Can not be determined

D. II and III

E. All of the Above

Answer –**A. I and II**

**Explanation :**

From Statement I and II,

Rahul’s age = x, His father’s age = 2x

x+5/2x+5 = 6/11

x=25 year**What was the profit earned on the CP by Ramesh by selling an article?**

I. He got 15% concession on labelled price in buying that article

II. He sold it for Rs.3060

C. Only either I or III and II together are required

D. All I, II and III together are required

E. None of the Above

Answer –**D. All I, II and III together are required**

**Explanation :**

Labelled price -x

From statement I, CP = 85% of x

From statement II and III, 2 = (3060 – x/ x)*100 x=3000

CP= 85% of 3000 = 2550

Thus All I, II and III together are required.**What will be the share of R in the profit earned by V, R and A together?**

I. They together invested an amount of Rs.54000 for a period of 1 year

II. R’s investment was 25% less than V’s and 50% more than A’s.

III. The profit of V is 4000 more than that of A.

A. I and II together

B. Only II

C. II and either I or III only

D. II and III together

E. None of the Above

Answer –**D. II and III together**

**Explanation :**

Let A’s investment = x

From statement II

R’s investment = 150% of x = 1.5x

V’s investment = z = R’s investment was 25% less than V’s = 75% of z = 1.5x => 2x

A, V, R profit ratio = x : 2x :1.5x = 2:4:3

Let profit ratio of A, V, R be 2y, 4y and 3y

From statement III

4y-2y = 4000

y =2000

R’ share = Rs.6000

Statement II and III together are sufficient to answer the question.
