SBI PO 2018 PYQs

Question 1

Directions: Instructions
Find the wrong number in given series sequence.

6, 12, 21, 33, 49, 66

Accepted Answer

The differences between consecutive terms are 6, 9, 12, 16, 17. The second differences are 3, 3, 4, 1. To maintain the pattern of +3, the sequence should be 6, 9, 12, 15, 18. Thus, 49 should be 33 + 15 = 48.

Question 2

Fill in the blank with the appropriate option.Although the medicine was once thought safe, _________ data has proven it to be harmful to children.

Accepted Answer

The sentence implies a change in understanding over time. 'Recent' data logically contradicts the past belief, making it the correct fit for the blank.

Question 3

Directions: Instructions
Find the wrong number in given series sequence.

6, 11.5, 19, 28.5, 41

Accepted Answer

The differences between consecutive terms are 5.5, 7.5, 9.5, 11.5. This forms an arithmetic progression with a common difference of 2. The last term should be 28.5 + 11.5 = 40, not 41.

Question 4

In each of the questions given below, four words are given in bold. These four words may or may not be in their correct position. The sentence is then followed by options with the correct combination of words that should replace each other in order to make the sentence grammatically and contextually correct. Find the correct combination of words that replace each other. If the sentence is correct as it is, select ‘5’ as your option.Countries (A)based on thecolour (B)of one's skin is a majorproblem (C)in India and a lot of otherdiscrimination. (D)

Accepted Answer

The words 'Countries' (A) and 'discrimination' (D) need to be swapped. The sentence should read: 'Discrimination based on the colour of one's skin is a major problem in India and a lot of other countries.'

Question 5

Fill in the blank with the appropriate option.In every workforce, there will be some people more _________ and thus better paid than others.

Accepted Answer

The sentence implies a positive quality leading to better pay. 'Capable' fits this context, meaning skilled and competent, justifying higher earnings.

Question 6

Directions: Instructions
Find the wrong number in given series sequence.

5, 26, 82, 214, 401, 702

Accepted Answer

The differences between consecutive terms are 21, 56, 132, 187, 301. The second differences are 35, 76, 55, 114. The pattern is 35, 70, 105, 140. So, 214 is incorrect; it should be 218.

Question 7

Fill in the blank with the appropriate option.His competence as an economist had been ______ by his successful fight against inflation.

Accepted Answer

The successful fight against inflation would confirm or establish his competence. 'Proved' fits this meaning perfectly, indicating his ability was demonstrated.

Question 8

Fill in the blank with the appropriate option.The headhunters faced problems in _________ suitably qualified scientific officers for national laboratories.

Accepted Answer

The correct word to fill the blank is 'finding'. It means to discover or locate, which fits the context of headhunters searching for qualified officers. The provided options are incorrect.

What is the average percentage of marks obtained by all students  in subject T ?

Accepted Answer

Sum the marks of all students in subject T. Divide this total by the number of students to find the average. Then, calculate this average as a percentage of the maximum marks for subject T.

Question 10

What approximate value will come in the place of the question mark ‘?’ in the following question?244.99 ÷ 4.99 + (40% of 1549.99) = 760 – ?

Accepted Answer

Approximate values: 245 ÷ 5 + (40% of 1550) = 760 - ?. This simplifies to 49 + 620 = 760 - ?, so 669 = 760 - ?. Thus, ? = 760 - 669 = 91.

Question 11

The ratio of the A's present age and B's age 4 years ago is 7 : 8. After 8 years, ratio of age of A to that of B is 9 : 11. Find the present age of B.

Accepted Answer

Let A's present age be 7x and B's age 4 years ago be 8x. So B's present age is 8x+4. Form equations for ages after 8 years: (7x+8)/(8x+4+8) = 9/11. Solve for x, then find B's present age.

Question 12

In the following number series, a wrong number is given. Find out the wrong number.5.9, 6, 6.1, 6.4, 7.9, 18.5, 112.9

Accepted Answer

The pattern is (previous number - 5)^2 + 6. The series should be 5.9, 6, 6.01, 6.02, 6.05, 6.14, 6.31. Thus, 18.5 is incorrect.

Marks obtained by ‘A’ in subject P, Q, & R together are  approximately what percent of marks obtained by F in subjects S, T & U together ?

Accepted Answer

Calculate A's total marks (P+Q+R) and F's total marks (S+T+U). Then, divide A's total by F's total and multiply by 100 to find the percentage. Round to the nearest whole number.

Question 14

In a 170 lt mixture of milk and water the ratio of milk and water is 12 : 5. If 20% of the mixture was taken out and 10 liters of water is added. Find the quantity of water in the new mixture.

Accepted Answer

Initial milk and water are 120L and 50L. After removing 20% mixture, 96L milk and 40L water remain. Adding 10L water makes total water 40+10 = 50L.

Question 15

In the following number series, a wrong number is given. Find out the wrong number.26, 27, 34, 58, 106, 186, 306

Accepted Answer

The differences between consecutive numbers are 1, 7, 24, 48, 80, 120. The second differences are 6, 17, 24, 32, 40. This pattern suggests the second difference should be 8, 8, 8, 8. Adjusting 27 to 28 makes the series consistent.

What is the overall percentage of marks obtained by ‘B’ in all subjects together (rounded off to two digits after decimal)?

Accepted Answer

Sum B's marks across all subjects and divide by the total maximum marks for all subjects. Multiply by 100 to get the percentage. Round to two decimal places.

Question 17

What approximate value will come in the place of the question mark ‘?’ in the following question?√74.01+43.01‌×4.99= 74.01 – ?

Accepted Answer

Approximate √74.01 as √74 ≈ 8.6. Approximate 43.01 as 43 and 4.99 as 5. The equation becomes 8.6 + 43 × 5 = 74 - ?. So, 8.6 + 215 = 74 - ?, which simplifies to 223.6 = 74 - ?. Thus, ? = 74 - 223.6 = -149.6. None of the options are correct. The question is flawed.

Question 18

The cost price of A is double the cost price of B. If the selling price of B is Rs. 3600 and the profit percentage is 20% then find the cost price of A.

Accepted Answer

First, calculate B's cost price: SP = CP * (1 + Profit%). So, 3600 = CP * 1.20, giving CP_B = 3000. Since CP_A is double CP_B, CP_A = 2 * 3000 = 6000.

Question 19

In the following number series, a wrong number is given. Find out the wrong number.1, 3, 9, 31, 129, 652, 3913

Accepted Answer

The pattern is (previous number × N) + (N-1). Following this, 129 × 5 + 4 = 649, not 652. Thus, 652 is the wrong number.
