The correct answer is Calicut.

Key Points

• Portuguese explorer Vasco Da Gama discovered the sea route from Portugal to India and came to India in 1498 at Calicut.
• He belonged to Portugal and the discovery of the sea route became essential as the Ottomans occupied Constantinople (present-day Istanbul) and stopped the trade through the land route.
• Vasco da Gama’s fleet arrived in Kappadu near Kozhikode (Calicut), on the Malabar Coast (present-day the Kerala state of India).
• The King of Calicut at that time was Samudiri (Zamorin).

Five colleagues - Chand, Chandini, Nidhi, Vikram and Ajay, are sitting in a row facing north.

1. Nidhi and Chandini occupy the extreme ends of the row.

2. Vikram is sitting exactly in the centre.

3. Ajay is sitting to the immediate left of Vikram.

4. No two people with the name starting with the same letter are immediate neighbours of each other.

Clearly, Chand and Chandini are not immediate neighbours of each other from the above statement.

Case II is eliminated following the above statement.

So, the final arrangement will be as shown below:

Clearly, Nidhi sits in the right extreme.

Hence, 'Nidhi' is the correct answer.

Given:

The ratio of incomes of A and B is 5 : 7

The ratio of their savings is 2 : 3

A and B spend ₹35,400 and ₹48,600

Concept used:

Savings = Income - Expense

Caclulation:

Let the income of A and B be 5x and 7x and savings 2y and 3y

According to the question,

5x - 2y = 35400 ----(i)

7x - 3y = 48600 ----(ii)

By multiplying 3 with eq (i) and 2 with eq (ii) we get,

15x - 6y = 106200 ----(iii)

14x - 6y = 97200 ----(iv)

By subtracting eq (iv) from eq (iii) we get

x = 9000

So, incomes of A = 9000 × 5 = Rs. 45000

Income of B = 9000 × 7 = Rs. 63000

Difference = 63000 - 45000

⇒ Rs. 18000

∴ The difference (in₹) between the incomes of B and A is 18000.

Alternate Method 

Now, according to the question,

(5x - 35400)/(7x - 48600) = 2/3

⇒ 15x - 106200 = 14x - 97200

⇒ x = 9000

Difference (in₹) between the incomes of B and A

7x - 5x = 2x = 2 × (9000) = 18000

Give:

∠BPC = 128°

Concept used:

In a ΔABC angle at the meeting points of internal angle bisectors of ∠B and ∠C = 90° + ∠A/2

Calculation:

According to the concept,

∠A/2 + 90° = ∠BPC

⇒ ∠A/2 + 90° = 128°

⇒ ∠A/2 = 128° - 90°

⇒ ∠A/2 = 38°

⇒ ∠A = 38° × 2 = 76°

∴ The measure of ∠A is 76°.

The pattern/logic followed here is:

According to the alphabetical positions of the letters,

The code for T will be 77 as it is immediately followed as well as preceded by a vowel.

Hence, ‘238977514’ is the correct answer.

Given:

The difference between 12% gain and 4% loss on sale of the item was ₹28

Concept used:

SP = CP + CP × gain%

SP = CP - CP × loss%

Here

SP = selling price

CP = cost price

Calculation:

Let the CP of the item be 100a

SP at 12% gain on CP = 100a + 100a × 12%

⇒ 112a

SP at 4% of loss on CP = 100a - 100a × 4%

⇒ 96a

According to the question,

112a - 96a = 28

⇒ 16a = 28

⇒ a = 28/16

Now, CP = 100 × (28/16)

⇒ Rs. 175

∴ The cost price of the item is Rs. 175.

The correct answer is 17.98.

Key Points

• The Global Birth Rate (crude) in the year 2020 is 17.98, according to World Bank.
• Birth rate of World went down by 1.13 % from 18.2 per 1,000 people in 2019 to 17.98 per 1,000 people in 2020.
• The world's total crude birth rate was estimated at 3,713.07 births per thousand population in 2020.
• The Global Birth Rate is used to calculate another fundamental measure, the rate of natural increase.​

Important Points

• Crude birth rate
  • indicates the number of live births occurring during the year, per 1,000 population estimated at midyear.
• Crude Death Rate
  • ​Calculated as the number of deaths in a given period divided by the population exposed to the risk of death in that period.
  • For human populations the period is usually one year.
• Subtracting the crude death rate from the crude birth rate provides the rate of natural increase, which is equal to the rate of population change in the absence of migration.

According to the alphabetical positions of the letters,

The logic followed here is:

(Sum of position value of consonant - sum of position value of vowel) ÷ 2 = code

The logic is:

Hence, ‘43’ is the correct answer.

By using the symbols in the table given below, we can draw the following family tree:

P @ Q $ U = R % S # V → P is the husband of Q, Q is the mother of U, U is the brother of R, R is the wife of S, S is the father of V.

Clearly, P is the Maternal grandfather of V.

Hence, ‘Maternal grandfather’ is the correct answer.

Given:

If 75% of a number is added to 75, then the result is the number itself.

Calculation:

Let the number be 100a

According to the question,

100a × 75% + 75 = 100a

⇒ 75a + 75 = 100a

⇒ 75 = 100a - 75a

⇒ 75 = 25a

⇒ a = 75/25 = 3

So, the number = 100 × 3

⇒ 300

∴ The number is 300.

Additional Information

Given:

A can complete a piece of work in 10 days

B is 25% more efficient than A.

Concept used:

Total work = efficiency of the worker × time taken by him

Calculation:

Let A's efficiency is 4a

So, B's efficiency = 4a + 4a × 25%

⇒ 5a

Now,

total work = 4a × 10

⇒ 40a

So, B will take to complete the task = 40a/5a

⇒ 8 days

∴ B alone will take 8 days to complete the same work.

Given:

Side ratio of the rectangle = 13 : 5

Area of the rectangle = 260 m²

Formula used:

Area of the rectangle = (l × b)

Perimeter of the rectange = 2(l + b)

l = length

b = breadth

Calculation:

Let the sides of the rectangle be 13a and 5a

According to the question,

13a × 5a = 260

⇒ 65a² = 260

⇒ a2 = 4

⇒ a = 2

So, sides are 13 × 2 = 26, and 5 × 2 = 10

Now,

Perimeter of the rectangle = 2(26 + 10)

⇒ 2 × 36 = 72

So, perimeter of the rectangle = 72 m

∴ The perimeter of the rectangular field is 72 m

BODMAS Rule:-

A. × and +

Given equation: 12 × 3 ÷ 4 + 6 - 2 = 20

After interchanging the signs, we get:

L.H.S = 12 + 3 ÷ 4 × 6 - 2

= 12 + 4.5 – 2

= 16.5 – 2

= 14.5 ≠ R.H.S

B. ÷ and +

Given equation: 12 × 3 ÷ 4 + 6 - 2 = 20

After interchanging the signs, we get:

L.H.S = 12 × 3 + 4 ÷ 6 - 2

= 36 + 0.67 – 2

= 36.67 – 2

= 34.67 ≠ R.H.S

C. + and –

Given equation: 12 × 3 ÷ 4 + 6 - 2 = 20

After interchanging the signs, we get:

L.H.S = 12 × 3 ÷ 4 - 6 + 2

= 9 – 6 + 2

= 11 – 6

= 5 ≠ R.H.S

D. × and ÷

Given equation: 12 × 3 ÷ 4 + 6 - 2 = 20

After interchanging the signs, we get:

L.H.S = 12 ÷ 3 × 4 + 6 - 2

= 16 + 6 – 2

= 22 – 2

= 20 = R.H.S

Hence, ‘× and ÷’ is the correct answer.

Given:

Sum = Rs. 19500

Rate = 10%

Time =  1 2/5 years

Concept used:

A = P(1 + r/100)ⁿ

Interest = A - P

A = amount

P = principal or sum

r = rate

n = time

Calculation:

Interest rate for 2/5 years = 10 × (2/5) = 4%

Now,

A = 19500(1 + 10/100)¹ × (1 + 10/100)^2/5

⇒ A = 19500(1 + 10/100) × (1 + 4/100)

⇒ A = 19500(1 + 1/10) × (1 + 1/25)

⇒ A = 19500(11/10) × (26/25)

⇒ A = 22308

So, interest of the given years = 22308 - 19500

⇒ Rs. 2808

∴ Required compound interest is Rs. 2808.

Given:

Sum = Rs. 850

Rate = 3.6%

Interest = 25.5

Concept used:

S.I = PTR/100

P = Principal or sum

R = rate

T = time

Calculation:

Let the time be a months

According to the question,

25.5 = [(850 × 3.6 × a)/(100 × 12)]

⇒ 25.5 = 2.55a

⇒ a = 25.5/2.55

⇒ a = 10

So, the actual time needs to get the interest = 10 months

∴ Required time to get the required interest is 10 months.
