What is the compound interest earned on 3rd year if Rs. 10000 is invested at the rate of 40% per annum?

Detailed Solution for CRPF Head Constable Mock Test - 3 - Question 26

Given:
Principal = Rs. 10000,

Compound interest earned on 3rd year = Amount received after 3 years – Amount received after 2 years.
In case of compound interest:

Where,
P = Principal, R = rate of interest and T = Time
And
CI = Amount – Principal
Applying the formula:
Amount received after 2 years = 10000 × ((1)+(40/100))2
= Rs. 19600
And
Amount received after 3 years = 10000 × ((1)+(40/100))3
= Rs. 27440
∴ Interest for the 3rd year = 27440 – 19600
= Rs. 7840.

⇒ 100% = 120 L
⇒ Out of 120 L, the concentration of water is 15L
⇒ Quantity of milk = 105 L
∴ Quantity added = 105 – 85 = 20 L.

Detailed Solution for CRPF Head Constable Mock Test - 3 - Question 41

Given:
Vikas's monthly salary is 20% more than Kausttav's monthly salary.
Rahul's monthly salary is 25000 more than Kausttav's monthly salary.
Their total monthly salary is 3,45000.
Calculation:
Let, Kausttav's monthly salary is 5x.
Then Vikas's monthly salary is 5x + 5x × (1/5) = 6x
So monthly salary of Rahul will be 5x + 25000
As per the question,
5x + 6x + 5x + 25000 = 3,45000
⇒ 16x = 3,20000
⇒ x = 20000
So the salary for kausttav is 20000 × 5 = Rs 100000
So the salary of Kausttav is Rs 100000

A pump fills 1,200 litres of water in a tank, after which it remains 60% empty. How much more water should go in to fill the tank to the brim?

Detailed Solution for CRPF Head Constable Mock Test - 3 - Question 43

Given:

480 persons working 10 hours per day complete one-fourth of a work in 10 days. How many additional persons are to be employed in order to complete the remaining work in 20 days, working 8 hours per day?

Detailed Solution for CRPF Head Constable Mock Test - 3 - Question 45

Given:
480 persons working 10 hours per day complete one-fourth of a work in 10 days.
Formula used:
M1 × D1 × H1/W1 = M2 × D2 × H2/W2
Where, M = Number of men,
D = Number of days, H = Number of hours,
W = Work done
Calculation:
Let, y additional workers are required;
M1 = 480, D1 = 10, H1 = 10, W1 = 1/4
M2 = (480 + y), D2 = 20, H2 = 8, W2 =  (1 − (1/4)) = 3/4
Using the above formula

⇒ 480 + y = 900
⇒ y = (900 − 480) = 420
∴ The required number of persons is 420.

The crystal clear, blue water and the magnificent sun make the Caribbean island of Saint Maarten a favorite vacation spot, one that is popular with North Americans during their winter holidays from December through March, as well as with South Americans and Europeans from April through August. The French and Dutch settled on the island in the 1600s, and to this day, the island is divided between the two of them. The French capital is Marigot; the Dutch capital is Philipsburg.
Tourists soon discover that St. Maarten has an intriguing history. Ancient artifacts found on the island date back to the Stone Age, 6,000 years ago! Tourists also learn that 1,200 years ago the Arawak Indians inhabited all the islands of the West Indies and were a peaceful people living under the guidance of their chiefs. Three hundred years after the Arawaks first arrived on St. Maarten, in the 1300s, they were defeated and forced to abandon the island by a hostile tribe of Indians originating in South America. This new tribe was called the Carib. The Caribbean Sea was named after them. Unlike the Arawaks, they had no permanent chiefs or leaders, except in times of strife. And they were extremely warlike. Worse, they were cannibalistic, eating the enemy warriors they captured. In fact, the very word cannibal comes from the Spanish name for the Carib Indians. The Spanish arrived in the fifteenth century and, unfortunately, they carried diseases to which the Indians had no immunity. Many Indians succumbed to common European illnesses; others died from the hard labor forced upon them.

Q. According to the article, present-day St. Maarten

Detailed Solution for CRPF Head Constable Mock Test - 3 - Question 64
• It is mentioned in the second last sentence of the first passage that the French and Dutch settled on the island in the 1600s, and to this day, the island is divided between the two of them.

• Options 2 and 4 have no supporting statements in the passage.
• The passage mentions that the Spanish arrived in the 15th century which is before the French and Dutch settled on the island. The passage does not mention anything about the Spanish whether they settled or not so option 1 is not correct.

Hence, the correct answer is option 3.

CRPF Head Constable Mock Test - 3 - Question 65

The crystal clear, blue water and the magnificent sun make the Caribbean island of Saint Maarten a favorite vacation spot, one that is popular with North Americans during their winter holidays from December through March, as well as with South Americans and Europeans from April through August. The French and Dutch settled on the island in the 1600s, and to this day, the island is divided between the two of them. The French capital is Marigot; the Dutch capital is Philipsburg.
Tourists soon discover that St. Maarten has an intriguing history. Ancient artifacts found on the island date back to the Stone Age, 6,000 years ago!

The Spanish arrived in the fifteenth century and, unfortunately, they carried diseases to which the Indians had no immunity. Many Indians succumbed to common European illnesses; others died from the hard labor forced upon them.

Q. Which of the following is NOT true about the Carib Indians?

Detailed Solution for CRPF Head Constable Mock Test - 3 - Question 65
• The second paragraph of the passage mentions that three hundred years after the Arawaks first arrived on St. Maarten, in the 1300s, they were defeated and forced to abandon the island by a hostile tribe of Indians originating in South America. This new tribe was called the Carib.
• The second paragraph gives many examples to prove how the Carib tribe was hostile as they practiced cannibalism with their enemies and were warlike.
• All the other options correspond to the above-mentioned sentences except for option 2 which describes Caribs as peaceful fishermen, hunters, and farmers. So option 2 is in contrast to facts and supporting examples mentioned about Caribs in the passage and hence not true.

​Hence, the correct answer is option 2.

So, option 3 is the correct answer.
Correct sentence: The teacher taught us that the earth is round.
