Which country has revoked its ratification of nuclear test ban treaty?
Detailed Solution for SSC CGL Tier 1 Mock Test - 18 - Question 28
The correct answer is Russia.In News

President Vladimir Putin signed off on a law revoking Russia's ratification of the Comprehensive Nuclear Test Ban Treaty, a move he says is designed to bring Moscow into line with the United States.Key Points

• Despite de-ratification, Russia maintains that it will refrain from resuming nuclear tests unless the United States initiates such action. The decision supposedly does not alter Russia's nuclear stance or its approach towards sharing information about its nuclear activities.
• The 1996 treaty, intended to end all nuclear explosions, was signed but never ratified by the U.S., prompting Putin to advocate for Russia, which had both signed and ratified the pact, to follow America's position.
• Concernings amid Western arms control experts suggest that Russia may be progressing towards a nuclear test as a form of intimidation in the midst of the Ukraine war. Russian officials, however, have downplayed this speculation.
• Putin refrained from confirming Russia's intentions on potential nuclear testing, despite calls from some Russian security experts and legislators for a nuclear bomb test to counter Western powers. A move like this could potentially set off a new era of nuclear testing among global powers, stirring fear among Western experts.
• The de-ratification law takes immediate effect following Putin's approval, noted on a government website, and having received endorsement from both the houses of Russia's parliament. Notably, no nuclear tests have been initiated post-Soviet Russia, with the last test from the Soviet Union in 1990 and the United States in 1992.

SSC CGL Tier 1 Mock Test - 18 - Question 31
The money multiplier in an economy increases with which one of the following?
Detailed Solution for SSC CGL Tier 1 Mock Test - 18 - Question 31

The correct answer is option 4.

Key Points

The money multiplier

• It is the amount of money created by commercial banks for a given fixed amount of base money and reserve ratio.
• An increase in the cash reserve ratio prevents the banks from lending more money and reduces the money multiplier.
• The Central Bank increases the reserve requirements for the Commercial banks. It will lead to a decrease in the money multiplier. Hence, Statement 2 is not correct.
• An increase in the banking habit of the population will increase the lending, thereby will lead to more deposits in the banking system, hence increasing the money multiplier. Hence, Statement 3 is not correct.
• Even if there is an increase in the population of the country, the money multiplier in an economy does not necessarily increase.
• The money created by the Federal Reserve is the monetary base, also known as high-powered money. Banks create money by making loans.
• A bank loans or invests its excess reserves to earn more interest.
• A one-dollar increase in the monetary base causes the money supply to increase by more than one dollar.
• The increase in the money supply is the money multiplier.
• The money multiplier increases with increasing capability with the banks to provide loans and this depends on the number of deposits available with the banks.
• More bank accounts and an increase in minimum balance requirement provide more deposits to the banks while more withdrawals and increase in reserve requirements reduce such deposits to be used for providing loans. Hence, Statement 1 is not correct, and Statement 4 is correct.
SSC CGL Tier 1 Mock Test - 18 - Question 32

Which of the following properties of water can be used to explain the spherical shape of rain droplets?

Detailed Solution for SSC CGL Tier 1 Mock Test - 18 - Question 32

Surface tension:

• Surface tension is the property by virtue of which liquid tries to minimize its free surface area.
• In a spherical shape, the surface area is minimum and for this reason, the raindrops are spherical.
• Surface tension is measured as the force acting per unit length of an imaginary line drawn on the liquid surface.

Surface tension

Two factors can affect the surface tension of a liquid. The factors are-

• Temperature: If temperature increases then the surface tension of a liquid decreases.
• Soluble Impurities: In the case of less soluble impurities, the surface tension decreases. But, for highly soluble impurities in the liquid the surface tension increases.

Detailed Solution for SSC CGL Tier 1 Mock Test - 18 - Question 55

Calculation:

Let the initial oranges with the fruit seller be x.

1st selling = 0.45x + 1

Remaining = x - (0.45x + 1) = 0.55x - 1

2nd selling =  × (0.55x - 1) = 0.11x - 0.2 + 2 = 0.11x + 1.8

Remaining after second selling = 0.55x - 1 - (0.11x + 1.8) = 0.55x - 0.11x - 1 - 1.8 = 0.44x - 2.8

3rd selling = 90% × (0.44x - 2.8)

Remaining after 3rd selling = 0.1 × (0.44x - 2.8) = 0.044x - 0.28

According to the question-

⇒ 0.044x - 0.28 = 5

⇒ 0.044x = 5.28

⇒ x =  = 120

The number of oranges was 120.

Alternate Method

At last, he sells 90% of the remaining oranges after selling the oranges to a second customer, then he has 10% of the remaining oranges.

10% of the remaining oranges after selling the oranges to the second customer = 5

So remaining oranges after selling the oranges to the second customer = 100% of the remaining oranges after selling the oranges to the second customer = 50 oranges

He gave 2 extra oranges to the second customer, so the remaining oranges = 50 + 2

He sells 20% of the remaining oranges to the second customer, so he has 80% of the remaining oranges = 52

100% of remaining oranges after selling the oranges to the first customer = (52/4) * 5 = 65 oranges

He gave 1 extra orange to the first customer, so the total oranges after selling 45% of the oranges = 65 + 1 = 66 oranges

(100% - 45% = 55%) of total oranges = 66

so

100% of oranges = (66/55) * 100 = 120 oranges
