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

**1.** (d)

From A, x + y = 5

From B, x^{2} – y^{2} = 15

From C, x – y = 3

To determine the no. of any two statements are necessary

**2.** (a)

Let the rate of interest be r%

Hence, any one of them is sufficient

**3.** (a)

From statement (A) and (C),

The person will take (21 – 3) 18 hrs, if he travels both ways by train. So it takes hrs if he travels one way by train. Hence, he will take (9 + 3) 12 hrs if he travels one way by bus.

So, required time = 12 × 2 = 24hrs

**4.** (d)

Since each statement provides data related to another one so any of the three statements is sufficient

**5.** (c)

Statement (A) gives the cost of fencing one metre of the plot.

Combining this with statement (B), total cost of fencing can be determined.

**6.** (b)

Quantity – I

C.P. = 160

S.P. = 184

Profit = 184 – 160 = 24

Profit%

∴ Profit% = 15 %

Quantity – II

M.P. = 2400

S.P. = 2016

Discount = 2400 – 2016 = 384

Discount%

Discount % = 16 %

∴ Quantity – I < Quantity – II

**7.** (e)

Quantity I = Quantity II or No relation can be established

Explanation:

Quantity I = 13 – 4 – 4 = 5 kmph

Quantity II = (13 – 3)/2 = 5km/hrs

**8.** (b)

∴ Quantity – I < Quantity – II

Quantity – I

Let the present age of A and B be 4x and 5x

∴ x = 5

∴ A’s present age = 20 yrs

Quantity – II

Average age of A, B and C = 24 years

Total = 24 × 3 = 72 years

Average age of B and C = 20 years

Total age of B and C = 20 × 2 = 40

Age of A = 72 – 40 = 32 years

**9.** (b)

Quantity I < Quantity II

Explanation:

X = 100 + 40/100 × 17500 = 24500

Y = 100 + 35/100 × 20000 = 27000

**10.** (e)

Explanation:

Quantity – I

Let speed of the Boat = x

Speed of the stream = 3 km/hr

7x^{2} – 144x – 63 = 0

7x^{2} – 147x + 3x – 63 = 0

∴ x = 21

Quantity – II

Bus stops = 8

Distance between bus stops = 1 km

Total distance = 1 × 7 = 7 km

Let speed of car = x

Time = 20 min

Hence, Quantity – II = Quantity – I

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

**1.** (e)

From statement I,

Let the number of students in the intitutes A and B be 3x and 4x respectively. However we get no conclusive answer by using data given in all the statements.

**2.** (c)

From statements I and II, Let Mr. X’s monthly income = ₹ x. Then

= ₹ 30000

From statements I and III,

= ₹ 30000

**3.** (a)

From Statements I and III, Let Suchitra’s son’s present age be x years.

∴ Suchitra’s present age = 2x years

After 4 years,

We can get the required answer by this relation.

So statement II is not required.

**4.** (d)

From all three statements, Seeta’s investment

= ₹ lakh = ₹ 93750

Geeta’s investment = ₹ 156250

Ratio of Neeta’s, Seeta’s and Geeta’s profit

= 85000 × 24 : 93750 × 18 : 156250 × 18

We can get the share of Neeta if total profit is given. So data given in all three statements is required to answer the question.

**5.** (d) Let the marked price of the article be ‘ x.

From statement II.

= ₹ 640

From statements I and III,

= ₹ 640

So statement II is sufficient to give the answer.

**Data Sufficiency Questions for IBPS PO 2013 Answers**

**1.** (b)

women can finish the work in 1 day

∴ 10 women can finish the work in 8 days.

From I and III,

Let 10 men can finish the work in x days and 10 women can finish the same work in y days.

Hence,

—— (i)

and from III – II,

—— (ii)

from (i) & (ii)

y = 8 days

Again from I and III

days

**2.** (a)

From I, Let present age of Sabir be x yr and age of his father be 2x yr.

From I and II,

x = 25 yr

From I and II, age of Sabir = 25 yrs.

Hence, only from I & II, age of Sabir and his father can be obtained.

**3.** (e)

Let two digit number be 10x + y.

From I, either

From II, x – y = 3 ⇒ y – x = 3

From III, x – y = 3

Hence, Even by (I) + (II) + (III) we cannot obtain the number.

**4.** (e)

From I, If P = 100

A = 200 and SI = 200 – 100 = 100

From II and III,

Hence, either I alone or II + III will be sufficient.

**5.** (e)

From I and II.

Length = 3x = 48 m

∴ x = 16

Breadth = 2x = 32 m

Hence, Area of floor = 48 ×32

Cost of flooring = 48 × 32 × 850 = ₹ 1305600

From I and III, 2(l + b) = 160

⇒ 2(3x + 2x) = 160 ⇒ 10x = 160

∴ x = 16

∴Length = 3 × 16 = 48 m

Breadth = 2 × 16 = 32 m

Cost of flooring = (48 × 32) × 850 = ₹ 1305600

Similarly, from II and III, we can find I = 48 m and b = 32 m

and Total cost of flooring = ₹ 1305600
