1 × 2 = 2 and 1 + 2 = 3

Here minimum value obtained is 2 when we replace @ by × sign.

Again, we know that if we add the numbers, the value obtained will be minimum, and if we multiply the numbers, the value obtained will be maximum.

So, replacing first @ by × and remaining @ by +, we get:

1 × 2 + 3 + 4 + 5

= 2 + 3 + 4 + 5

= 14

Therefore, the minimum value of '1@2@3@4@5' is 14.

Hence, ‘14’ is the correct answer.

The logic is:

Sun : Earth → Earth revolves around the sun.

Similarly,

_______ : Moon → The moon orbits the Earth.

Hence, ‘Earth’ is the correct answer.

Given:

Concept:
Follow the BODMAS rule to solve this question, as per the order given below:

Calculation:

⇒ ? = 62 ÷ 5 - (16/7) × 7/5 + 5/4 × 16/25

⇒ ? = 62/5 - 16/7 × 7/5 + 5/4 × 16/25

⇒ ? = 62/5 - 16/5 + 4/5

⇒ ? = 62/5 + 4/5 - 16/5

⇒ ? = 66/5 - 16/5

⇒ ? = 50/5

∴ ? = 10

Mean of 150 items = 45

Formula:

Average = (Sum of elements)/(Number of terms)

Calculation:

Sum of 150 items = 45 × 150 = 6750

Corrected sum of 150 items = 6750 - (83 + 76) + (38 + 46) = 6675

∴ Correct mean = 6675/150 = 44.5

Given:

The ratio of train, bus, airfares = 5 : 8 : 12

The ratio of passengers traveling by train, bus, air = 3 : 4 : 5

Total fair collected for single trip = Rs.107000

Calculation:

Compound ratio of fares and number of travelers of train, bus and air =

= 5 × 3 : 8 × 4 : 12 × 5

= 15 : 32 : 60

Fare collected from air passengers = 60/(15 + 32 + 60) × 107000 = 60000

∴ Fare collected from air passengers is Rs.60000.

Hint

Compound ratio: When two or more ratios are multiplied term-wise, the ratio thus obtained is called compound ratio.

Two ratios = m : n and a : b

compound ratio = ma : nb

Given:

⇒ ? = √150 - √54 - √24

Calculation:

⇒ ? = √(25 × 6) - √(9 × 6) - √(4 × 6)

⇒ ? = √(5 × 5 × 6) - √(3 × 3 × 6) - √(2 × 2 × 6)

⇒ ? = 5√6 - 3√6 - 2√6

⇒ ? = √6(5 - 3 - 2)

∴ ? = 0

The correct answer is AB+.
Key Points

• Type AB-positive blood is called the "universal recipient" type because a person who has it can receive blood of any type.
• Individuals with type O Rh D negative blood are often called universal donors.
• However, these terms are only generally true with respect to possible reactions of the recipient's anti-A and anti-B antibodies to transfused red blood cells, and also possible sensitization to Rh D antigens.

Given:

Total number of students in auditorium = 6889

Calculation:

Let the number of students and number of rows be n.

⇒ n × n = 6889

⇒ n = √6889

⇒ n = 83

∴ There are 83 rows in the auditorium.

Given:

A + B + C = 1/5

B + C + D = 1/10

C + D + A = 1/15

D + A + B = 1/30

Calculation:

Adding all above equations,

3(A + B + C + D) = 1/5 + 1/10 + 1/15 + 1/30

3(A + B + C + D) = 12/30

(A + B + C + D) = 2/15

∴In 15/2 = days work will be completed when all four worked together.

Given expression: 25 + 48 × 6 ÷ 12 – 2

After replacing the symbols by their meaning, we get:

25 - 48 ÷ 6 + 12 × 2

= 25 – 8 + 24

= 49 – 8

= 41

Hence, ‘41’ is the correct answer.

The logic is:

Hence, ‘0’ is the correct answer.

Main Statement:

Whenever Sakshi hears it's someone's birthday, she orders a cake.

Options:

1. DB

D. Sakshi did not ordered a cake.

B. Sakshi did not hear of someone's birthday.

The ordered pair of statements is logically consistent with the main statement.

Sakshi did not ordered a cake because Sakshi did not hear of someone's birthday. (As, whenever Sakshi hears it's someone's birthday, she orders a cake)

2. BD

B. Sakshi did not hear of someone's birthday.

D. Sakshi did not ordered a cake.​

The ordered pair of statements is logically not consistent with the main statement.

Whenever Sakshi hears it's someone's birthday, she orders a cake. So, Sakshi did not hear of someone's birthday, the later is known from the main statement. The statement D is unnecessary.

3. AB

A. Sakshi heard of someone's birthday.

B. Sakshi did not hear of someone's birthday.

The ordered pair of statements is logically not consistent with the main statement.

The pair of statements have absurd meaning.

4. CA

C. Sakshi ordered a cake.

A. Sakshi heard of someone's birthday.

The ordered pair of statements is logically not consistent with the main statement.

Whenever Sakshi hears it's someone's birthday, she orders a cake. So, Sakshi ordered a cake because of the fact we know from the main statement. The statement A is unnecessary.

Hence, ‘DB’ is the correct answer.

Confusion Points
The options "AB" and "DB" are not the same. This is because in the direction of the question it is mentioned that the options are ordered pairs.

A. (i) All shops are showrooms.

(ii) No showroom is a mall.

(iii) All shops are not malls. → True (As, All shops are showrooms and No showroom is a mall → All shops are not malls)

B (i) No Japanese can dance.

(ii) All Americans are books.

(iii) Americans and Japanese can dance. → False (As, there is no definite relation between Americans and Dance. Hence, false and No Japanese can dance)

C. (i) No P is Q.

(ii) No Q is R.

(iii) No P is R. → False (As, there is no definite relation between P and R. Hence, false)

Hence, ‘Only A’ is the correct answer.

Calculation:
Total number of web series released by subscription from 2015 to 2018
⇒ 35 + 35 + 42 + 48 = 160
⇒ 160/4 = 40

Code of each word is shown below:

The code of 'get up go there' be written as:
get - ju
up - fa
go - ka
there - na
Hence, ‘fa ju ka na’ is the correct answer.

Calculation:

Cost price of all five goods = 173 + 219 + 350 + 481 + 227 = Rs.1450

Total selling price of all five goods for shopkeeper X = 180 + 220 + 360 + 490 + 250 = Rs.1500

Total selling price of all five goods for shopkeeper Y = 175 + 225 + 357 + 500 + 235 = Rs.1492

Profit % of shopkeeper X = (1500 - 1450)/1450 × 100 = 3.45%

Profit % of shopkeeper Y = (1492 - 1450)/1450 × 100 = 2.90%

∴ Shopkeeper X have more profit percentage, which is 3.45%.

The logic is as follows:

243 → This number is multiple of 3.

280 → This number is multiple of 7, 5 and 2.

172 → This number is multiple of 2.

230 → This number is multiple of 2, 5 and 23.

92 → This number is multiple of 2 and 23.

41 → This number is a prime number.

14 → This number is multiple of 2 and 7.

Hence, 41 is the odd one out.

Note: For this question, discrepancy is found in the question paper so we have improvised this question.
