Hindi General Knowledge Test! Trivia Questions Quiz

Explanation
The given equation states that the ratio of x to y is equal to the ratio of y to z. From the given options, the equation 3x=7y can be rearranged to x=y/3 and 5y=9x can be rearranged to x=y/1.8. By comparing these two equations, we can see that x is equal to z. Therefore, the correct answer is x=z.

Explanation
Rajasthan is the correct answer because it is the leading state in cement production in India. Rajasthan has abundant limestone reserves, which is a key raw material for cement production. The state has several cement plants, including major players like UltraTech Cement and Shree Cement. These factors contribute to Rajasthan's top position in cement production in the country.

Explanation
The correct answer is Core. The core is the innermost layer of the Earth, located beneath the mantle. It is primarily made up of iron and nickel and is divided into two parts: the outer core and the inner core. The outer core is liquid, while the inner core is solid. The core plays a crucial role in generating the Earth's magnetic field and is responsible for the movement of tectonic plates.

Explanation

Explanation
The question asks about the carat weight of pure gold. Gold is often measured in carats, with 24 carats being the highest purity level. Therefore, the correct answer is 24.

Explanation
If the ratio of A and B is 3:2 and they are divided into 1000, then A will receive 3/5 of the total and B will receive 2/5 of the total. Therefore, A will receive (3/5) * 1000 = 600.

Explanation
The train is 300 meters long and it takes 33 seconds to pass a man walking in the same direction. To find the speed of the train, we need to convert the time taken to hours. 33 seconds is equal to 33/3600 hours. The distance covered by the train in this time is 3 km. Therefore, the speed of the train is (3 km)/(33/3600 hours) = 100*(3/33) km/h = 9 1/11 km/h. Adding this to the walking speed of the man, we get 9 1/11 + 26 7/11 = 35 8/11 km/h.

Explanation
The given equation states that the ratio of x to y is equal to the ratio of y to z. From the given options, the equation 3x = 7y can be simplified to x = (7/3)y. Similarly, the equation 5y = 9x can be simplified to y = (9/5)x. By comparing these two equations, we can conclude that x and z are equal, as x = (7/3)y and y = (9/5)x can be rearranged to x = z. Therefore, the answer is x = z.
