Question 1

What approximate will come in the place of the question mark ‘?’ in the following question?244.03 – 654.02 + ? ÷ 2.01 = 835.01

Accepted Answer

Approximate the numbers: 244 - 654 + ? / 2 = 835. This simplifies to -410 + ? / 2 = 835. So, ? / 2 = 1245, which means ? = 2490.

Question 2

144 added to 40% of a number results in 188. Find the number.

Accepted Answer

Let the number be x. The equation is 144 + 0.40x = 188. Subtract 144 from both sides to get 0.40x = 44. Divide 44 by 0.40 to find x = 110.

Question 3

In the following number series, a wrong number is given. Find out the wrong number.330, 80, 280, 120, 250, 130, 240

Accepted Answer

The series has two alternating patterns: 330, 280, 250, 240 (decreasing by 50, 30, 10) and 80, 120, 130 (increasing by 40, 10). The first series should be 330, 280, 230, 220. Thus, 250 is wrong.

What are the average marks obtained by out of 80 by all the six  students together in subject ‘Q’?

Accepted Answer

Sum the marks of all six students in subject Q: 70+60+50+80+70+40 = 370. Divide by 6 students: 370/6 = 61.66, which rounds to 62.

Question 5

What approximate value will come in the place of the question mark ‘?’ in the following question?65.01 -‌3√512+ 249 = ? – 240

Accepted Answer

Approximate 65.01 to 65. The cube root of 512 is 8. The equation becomes 65 - 8 + 249 = ? - 240. Simplify to 306 = ? - 240. Add 240 to both sides to get ? = 546.

Question 6

A sum of Rs. X was invested in a scheme at the rate of 10% calculated on simple interest for 3 years and the amount received is further invested into another scheme for 2 years at a rate of 20% compounded annually. If the final amount received is Rs. 12168, then find the value of X.

Accepted Answer

First, calculate the amount after 2 years with compound interest: A = P(1 + R/100)^T. Then, use this amount as the principal for simple interest: A = P(1 + RT/100) to find X.

Question 7

In the following number series, a wrong number is given. Find out the wrong number.291, 147, 75, 39, 22, 12, 7.5

Accepted Answer

The pattern is (Previous Number - 3) / 2. Applying this, 39 should lead to (39-3)/2 = 18. The given number is 22, making it the wrong one.

Question 8

Directions: Reasoning
Instructions
Study the following information to answer the given questions. Eight Mends — A, B, C, D, L, M, N and O are seated in a straight  line, but not necessarily in the same order. Some of them are facing north while some are facing south. Only three people sit to the left of N. B sits second to the right of N. C sits third to the left of O. O is not an immediate neighbour of B. O does not sit at any of the extreme ends of the line. C and O face same direction (i.e., if C faces north then O also faces north and vice versa.) Both the immediate neighbours of D face north. D does not sit at any of the extreme  ends of the line. Person sitting at extreme ends face opposite directions (i.e., if one person faces north then the other faces south and vice-versa.) Both the immediate neighbours of N face same direction (i.e., if one neighbour faces  north then the other also faces north and vice versa.)
A sits second to the left of L. D faces a direction opposite to L. (i.e.  if L faces north then D faces south and vice-versa.)

How many people sit exactly between B and O ?

Accepted Answer

To find the number of people between B and O, we need the full seating arrangement. Once the arrangement is established, count the individuals positioned directly between B and O.

Question 9

What will come in the place of the question mark ‘?’ in the following question?√289 – 15% of 300 = ?2– 284

Accepted Answer

Calculate √289 as 17. Find 15% of 300, which is 45. The equation becomes 17 - 45 = ?² - 284. Simplify to -28 = ?² - 284. Add 284 to both sides: ?² = 256. Thus, ? = √256 = 16.

Question 10

Find out the approximate value which should replace the question mark (?) in the following question.1/7.99 + 1/11.96 – 1/3.94 + 1/? = 0

Accepted Answer

Approximate the decimals to whole numbers: 1/8 + 1/12 - 1/4 + 1/? = 0. Find a common denominator (24). (3+2-6)/24 + 1/? = 0. This simplifies to -1/24 + 1/? = 0, so 1/? = 1/24, thus ? = 24.

Question 11

What approximate value will come in the place of the question mark ‘?’ in the following question?2?= 32.01 ÷ 128.01 × 1023.97 ÷ 7.97

Accepted Answer

Approximate the values: 32 ÷ 128 × 1024 ÷ 8. This simplifies to 1/4 × 128 = 32. Since 2^5 = 32, the value of '?' is 5.

O is not an immediate neighbour of B. O does not sit at any of the extreme ends of the line. C and O face same direction (i.e., if C faces north then O also faces north and vice versa.) Both the immediate neighbours of D face north. D does not sit at any of the extreme  ends of the line. Person sitting at extreme ends face opposite directions (i.e., if one person faces north then the other faces south and vice-versa.) Both the immediate neighbours of N face same direction (i.e., if one neighbour faces  north then the other also faces north and vice versa.)
A sits second to the left of L. D faces a direction opposite to L. (i.e.  if L faces north then D faces south and vice-versa.)

Who amongst the following represent the immediate neighbours of the persons sitting at the extreme ends of the line ?

Accepted Answer

Identify the persons at the extreme ends of the line. Their immediate neighbours are the persons sitting next to them. Based on the arrangement, D and O are the correct neighbours.

Question 13

A invests Rs. 2800 and B invests Rs. 2100 in a business, A withdraws his money after 6 months while C invested 25% of A's capital after 4 months when A withdraws his money and B invests for the whole year, if annual profit of is Rs. 930, then find B's share.

Accepted Answer

Calculate the investment ratio for A, B, and C based on their capital and time. A: 2800*6, B: 2100*12, C: (2800*0.25)*8. Simplify the ratio and distribute the total profit of Rs. 930 accordingly to find B's share.

Question 14

Find out the approximate value which should replace the question mark (?) in the following question.39.96% of (198.99 + 5.992) = ?

Accepted Answer

Approximate 39.96% to 40%, 198.99 to 199, and 5.992 to 6. The expression becomes 40% of (199 + 6) = 40% of 205. Calculate 0.40 * 205 = 82. The closest option is 94.

Question 15

What approximate value will come in the place of the question mark ‘?’ in the following question?339.98 ÷ ? = √143.98 + √64.02

Accepted Answer

Approximate 339.98 to 340, √143.98 to √144 (12), and √64.02 to √64 (8). The equation becomes 340 ÷ ? = 12 + 8 = 20. So, ? = 340 ÷ 20 = 17.

Both the immediate neighbours of N face same direction (i.e., if one neighbour faces  north then the other also faces north and vice versa.)
A sits second to the left of L. D faces a direction opposite to L. (i.e.  if L faces north then D faces south and vice-versa.)

Who amongst the following faces north ?

Accepted Answer

To determine who faces north, analyze the seating arrangement and relative positions. Based on the given information, N is positioned such that their face is directed towards the north.

Question 17

A whole-seller after allowing a successive discount of 20% and 10% on the list price of a product get a profit of Rs. 120. find the cost price of the product, If list price of the product is Rs. 1000.

Accepted Answer

Calculate the selling price after successive discounts: 1000 * 0.80 * 0.90 = 720. Since profit is 120, cost price = selling price - profit = 720 - 120 = 600.

Question 18

Find out the approximate value which should replace the question mark (?) in the following question.17.01+23.04‌‌–48.01÷√4.03=?2

Accepted Answer

Approximate the values: 17 + 23 - 48 ÷ √4. This simplifies to 17 + 23 - 48 ÷ 2, which is 17 + 23 - 24 = 40 - 24 = 16. Since the question asks for ?^2, then ?^2 = 16, so ? = 4.

Question 19

What approximate value will come in the place of the question mark ‘?’ in the following question?34.03% of 550.08 ÷ ? = 297.08 + √728.97 - √89998

Accepted Answer

Approximate the values: 34% of 550 ÷ ? = 297 + √729 - √90000. This simplifies to 187 ÷ ? = 297 + 27 - 300, so 187 ÷ ? = 24. Thus, ? ≈ 187/24 ≈ 7.79, which is approximately 8.
