Data Sufficiency Questions PDF for SBI PO Pre 2020 | Data Sufficiency For SBI PO

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:
» Explain it
E
If circum radius in the statement 1 is given then hypotenuse will be double of the circum radius.

From the statement II, one angle is 60 degrees then other will be 30 degrees. Here we know all the angles and by combining with the statement I, we can conclude one side that is hypotenuse

By using sin 60 = height/hypotenuse we can conclude the other side then after we can easily conclude the area of the triangle.

Hence, option E is correct.
 
» Explain it
E
5 years before, let the age of moni = x then the age of soni = x – 5 
 
At present, their age will be, Moni = x + 5 years, Soni = x – 5 + 5 = x years 
 
In the statement II, the ratio of x + 5 and x are given therefore, by combining both the statement, we can conclude our answer.  

Hence, option E is correct
 
» Explain it
D
If we combine both the statement, then we can conclude their speed as 24 m/sec and 12 m/sec.

Now we can conclude the sum of their length but the difference of their lengths is not possible to get.

Therefore, the data in both the statements I and II is not sufficient to answer the question.

Hence, option D is correct.
 
» Explain it
A
From the question, the unit digit of the three-digit number is 3, and it is divisible by 7.

From the statement I, the number is divisible by 9

LCM of 9 and 7 = 63

The only number which is multiple of 63 and the unit digit of which is 3, is 63 × 11 = 693

Therefore, we can conclude our answer by this statement

From the statement II, the number is divisible by 21 therefore, LCM of 21 and 7 = 21

There are many numbers like, 273, 483 ------ which is divisible by 21 and 7, and the unit digit of which is 3

Therefore, we could not get a unique answer by this statement.
Therefore, the data in statements I alone is sufficient to answer the question, while the data in statement II alone is not sufficient to answer the question.

Hence, option A is correct.
 
 
» Explain it
D
In none of the statement or in question, it is given any information about number therefore by using only percentage, we could not conclude our answer.

Hence, option D is correct.
