Questions on Data Sufficiency for SBI PO 2019, IBPS PO 2019 | Data Sufficiency Questions for SBI PO PDF at Smartkeeda

Directions: 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 both the statements and give answer:
1
Find the distance travelled by Rajdhani express in two hours if it travels with its original speed?
 
Statement I :  The train started from the origin station 20.25 hours later than the scheduled time towards its destination which is 750 km away from the origin.
 
Statement II : To reach the destination station in the scheduled time the loco – piolet of the train increases the speed of the train to 125% of the original speed. 
» Explain it
E
From I and II:

Let the original speed of the train is ‘100x’ km/h

Increased speed = 125% of 100x = 125x km/h

According to question-

⇒  750  –  750  = 20.25
100x 125x

⇒ x =  2
3

Original speed of the train = 100x
= 100 ×  2  =  200  km
3 3

Hence the distance travelled by train in 2 hours
= 2 ×  200  =  400  km
3 3

Hence statements I and II together are sufficient.

Therefore, option (E) is correct.
2
What should be the selling price of washing machine so as to make a profit of 25%?
 
Statement I : An electronic shop dealer marks washing machine 80% above the cost price and after allowing a discount of 25% he claims a profit of Rs. 3500.
 
Statement II :  A shopkeeper sold the same washing machine for Rs. 15000 on the condition that shopkeeper will pay the transportation cost of Rs 2000 and he gets a profit of 25%.
» Explain it
C
From Statement I : Let the cost price of the working machine be x.

then the marked price of washing machine
= x +  80  × x = 1.8x
100

Selling price = 1.8x ×  100 – 25  = 1.35x
100

Now, profit = 1.35x – x

Profit = 0.35 x

but

0.35x = 3500

∴ x = 10,000

So, the cost price of the washing is Rs. 10000. Selling price in order to earn 25% profit
125  × 10000 = 12,500
100

Hence, statement I alone is sufficient

From Statement II:

Let the cost price of the washing machien be x

then,

Cost price after paying transportation = x + 2000

then
⇒  x + 2000  =  100
15000 125

⇒ x + 2000 = 12000

⇒ x = 10000

Cost price is Rs. 10000

Selling price in order to earn 25% profit
125  × 10000= Rs. 125000
100

Hence, statement II alone is also sufficient.

Here, Statement I or II alone is sufficient.

Therefore, option (C) is correct.
» Explain it
C
From Statement I :

Using the information given in above statement.

Anuj + 14 = Ankur

Here, we have no information about p and the actual age of Anuj.

So, we cannot find the answer.

Hence, statement I alone is not sufficient.

From Statement II:

Using the information given in above statement, we can say that

Anuj + ankur = p

Here, we have no information about the present age of Anuj

So, we cannot find the answer.

Both Statement I and II :–

From statement I : Anuj + 14 = Ankur

From Statement II : Anuj + Ankur = p

2 Anuj + 14 = p

Here, cannot find the actual age of Anuj and the real value of p.

So, we cannot find the answer.

Hence, Both statement I and II together are not sufficient.

Hence, option (D) is correct.
» Explain it
D
Let the length of layer piece, middle piece and shorter piece be l, m and s respectively.

From Statement I :

Using the information given in above statement.

l + m = 17

Here, we have no information about the total length of the rope or the length of shorter piece.

So, we cannot find the answer.

Hence, statement I alone is not sufficient.

From Statement II:

Using the information given in above statement, 

s + m = 19

Here, we have no other information about the length of these pieces.

So, we cannot find the answer.

Hence, statement II alone is not sufficient.

Both Statement I and II :–

From statement I : l + m = 17

From Statement II : s + m = 15

Combining both statement I and II we get 

l – s = 2

At this point, we have no information about total length or the length of any of these pieces of the rop.e

So, we cannot find the answer.

Hence, Both statement I and II together are not sufficient.

Hence, option (D) is correct.
» Explain it
C
From the question, A : B = 1 : 3 
 
Statement I : after 10 years, the ratio will become 5 : 11 
 
Statement II : 5 years ago, the ratio was 1 : 4 
 
Therefore, statement I or Statement II alone is sufficient to get our answer, and their ages will be 15 years and 45 years respectively
 
Hence, option C is correct.
