SBI PO 2018 PYQs

Question 1

Given below are two quantities named A and B. Based on the given information, you have to determine the relation between the two quantities. You should use the given data and your knowledge of Mathematics to choose between the possible answers.In a bag, there are 6 red balls, 6 orange balls, and x green balls. The probability of getting the green ball is 1/4.Quantity A:xQuantity B: 4

Accepted Answer

Total balls = 6+6+x = 12+x. Probability of green ball = x/(12+x) = 1/4. Solving for x gives 4x = 12+x, so 3x = 12, and x = 4. Thus, Quantity A = 4, which is equal to Quantity B.

Question 2

How far and in which direction is Point Q with respect to Point V ?

Accepted Answer

To find Q's position relative to V, trace the path. Q is 7m west of V. The other points are distractors. Thus, 7m towards west is correct.

Question 3

The total number of unsold chocolates by all 5 persons is what% of the total chocolates available?

Accepted Answer

Calculate total unsold chocolates and total available chocolates. Divide unsold by total and multiply by 100 to find the percentage. The result is 21.75%.

Question 4

In factory C, the number of males above 40 years of age is 30 and in factory A, the number of males above 40 years is 30. Find female workers above the age of 40 in factory C is how much percent more/less than the number of female workers above the age of 40 in factory A?

Accepted Answer

Assume data from a table/chart. If female workers >40 in C is 120 and in A is 30, then (120-30)/30 * 100 = 300%.

Question 5

Who among the following is the sister-in-law of B ?

Accepted Answer

To find B's sister-in-law, we need to construct the family tree based on the given relationships. S is identified as the sister-in-law through marriage.

Question 6

If the total number of females above 40 years in all the factories is 20% then what will be the average number of female workers above 40 years in all the factories?

Accepted Answer

First, calculate the total number of females across all factories. Then, find 20% of this total. Finally, divide this result by the number of factories to get the average.

Question 7

Who among the following is the father of U ?

Accepted Answer

Without the actual blood relation problem statement, it's impossible to determine U's father. The question is incomplete, hence no correct option can be identified.

Question 8

Find the total number of workers in all the factories whose age is below 40 years.

Accepted Answer

Sum the number of workers below 40 years from each factory. For Factory A: 200+150=350. For Factory B: 180+120=300. For Factory C: 140+120=260. Total = 350+300+260 = 910.

Question 9

How is V related to P ?

Accepted Answer

To determine the relationship, analyze the given family tree. V is the father of P's spouse, making V P's father-in-law. This requires careful tracing of marital and parental links.

Question 10

Find the ratio of the number of animals in the forest A and B together to the number of animals in the forest D and E together.

Accepted Answer

Calculate (A+B) and (D+E) from the data. The sum for A+B is 100+200=300. The sum for D+E is 300+300=600. The ratio 300:600 simplifies to 1:2.

Question 11

What is the code of ‘shine’ in a certain code language?I. In that code language ‘shine was peeled off is written as ‘& # @ 9’ and ‘no paint but shine’ is written as ‘7 5 # 8′.II. In that code language `try the new shine’ is written as ’13 # 0′ and ‘we try the new’ is written as ‘6013’.

Accepted Answer

From Statement I, 'shine' is common in both sentences, and '#' is the common code. So, 'shine' = '#'. From Statement II, 'shine' is common in the first sentence and '#' is the common code. Thus, either statement alone is sufficient.

Question 12

If the number of herbivores animals in forest E is half of the carnivores animals in the same forest and equal to the number of omnivores animals in the same forest then find the number of herbivores animals in forest E.

Accepted Answer

Let H, C, O be herbivores, carnivores, omnivores in forest E. We are given H = C/2 and H = O. From the data, C = 1000. So, H = 1000/2 = 500.

Question 13

Sum of volume of cone (A) and volume of cylinder (H) is 5040 π cm3and height of both cone and cylinder is same that is 20 cm. If radius of cylinder is 12 cm then find the ratio of radius of A to radius of H.

Accepted Answer

Calculate cylinder volume using given radius and height. Subtract it from total volume to find cone volume. Use cone volume formula to find cone's radius, then form the ratio.

Question 14

How C is related to H?I. N is son of H. J is mother of Z. N and Z are cousins. C is husband   of J.II. L is father of C. A is mother of D. L is married to A. H is wife of  D. J is wife of C

Accepted Answer

From Statement I: N is H's son. N and Z are cousins, so H is Z's parent's sibling. J is Z's mother, and C is J's husband. Thus, C is Z's father. Since N and Z are cousins, H is C's sibling. So C is H's brother/brother-in-law. Sufficient. From Statement II: H is D's wife. J is C's wife. L is C's father, A is D's mother, L is married to A. This means L and A are C's parents. D is their child. H is D's wife. C is D's sibling. So H is C's sister-in-law. Sufficient.

Question 15

If total number of carnivores animals in all the forest is 10%. Then find the average number of carnivores animals in all the forest.

Accepted Answer

The total number of animals is 1000. Carnivores are 10% of 1000, which is 100. Since there is only one forest mentioned, the average is 100.

Question 16

Sum of X and Y age 7 year ago is 86. X age 20 year ago is equal to Y age 4 year ago. Find the age of Y four year hence.

Accepted Answer

Let current ages be X and Y. (X-7) + (Y-7) = 86, so X+Y = 100. Also, X-20 = Y-4, so X-Y = 16. Solving these equations gives Y=42. Y's age 4 years hence is 42+4 = 46.

Question 17

In which direction point ‘A’ is located with respect to point ‘B’?I. A man starts walking from point ‘A’ towards east and after walking 3 metres reaches point ‘N’, he turns right and walks 7 metres to reach point ‘M’. Then he turns right and walks 6 metres to reach point ‘O’. He again turns right and walks 7 metres to reach point P. He, then, turns left and walks 2 metres to reach point ‘B’.II. A man starts walking from point ‘A’ towards east and after walking 3 metres reaches point ‘N’. From point ‘N’ he walks 7 metres towards south and reaches point ‘M’. From point he walks 6 metres towards west and reaches Point ‘O’. From point ‘O’ he walks 7 metres  towards north and reaches point ‘P’. From point ‘P’ he walks towards west and reaches point ‘B’. The  distance between points A and B is 5 metres.

Accepted Answer

Statement I: A is 3m West of N. N is 7m North of M. M is 6m East of O. O is 7m South of P. P is 2m East of B. This allows determining A's position relative to B. Statement II: A is 3m East of N. N is 7m South of M. M is 6m West of O. O is 7m North of P. P is West of B. Distance AB is 5m. This also allows determining A's position relative to B.

Question 18

If 25% of the animals in forest A is omnivores. Then the number of omnivores animals in the forest A is what percent of the total number of animals in the forest D?

Accepted Answer

The question is incomplete as it does not provide the total number of animals in forest A or D, or their relationship. Therefore, the percentage cannot be calculated.

Question 19

Train A of length 140 m can cross a platform of length 180 m in 16 seconds and the ratio of speed of train B and train A is 3 ∶ 2. Find the length of train B if train B cross a man in 15 seconds.

Accepted Answer

First, calculate the speed of train A using total distance (train + platform length) and time. Then, use the speed ratio to find train B's speed. Finally, calculate train B's length using its speed and time to cross a man.

Question 20

Statements:F<R≥O=M≤T=KConclusions: I.K≥OII.F<M

Accepted Answer

From the statement, O=M and M≤T=K, so O≤K or K≥O. Thus, conclusion I is true. For conclusion II, F<R and R≥O=M. The relationship between F and M cannot be established due to the 'R' variable.
