Basic Maths And Science MCQ Quiz

Shruti initially had 15 apples. Her mother gave her 6 more, so she now has a total of 21 apples.

Jatin initially had 10 bottles of jam. He gave 4 bottles to his sister and 5 bottles to his mother, which means he gave away a total of 9 bottles. Therefore, he is left with only 1 bottle of jam.

The statement "Sun is the coldest object" is false. The Sun is actually one of the hottest objects in our solar system. It is a giant ball of gas that emits heat and light through nuclear fusion. The temperature at the Sun's core is estimated to be around 15 million degrees Celsius, making it extremely hot. Therefore, the correct answer is False.

The correct answer is eleven because Rupesh initially had 5 notebooks and his mother gave him 6 more notebooks. Therefore, the total number of notebooks with Rupesh is 5 + 6 = 11.

The correct answer is "planet" because Earth is indeed the third planet from the sun. The word "planet" is spelled with a lowercase "p" in the options, but it is still correct since it refers to the same celestial body. The capitalized "Planet" option is also correct because it is a valid alternative way of writing the word.

During the day, the brightness of the sun outshines the light emitted by the stars and moon, making them invisible to the human eye. The sun's rays scatter in the Earth's atmosphere, creating a blue sky, which further obscures the visibility of stars and the moon. Therefore, it is true that stars and the moon are not visible during the day.

Soluble objects are substances that can dissolve or mix with water. This means that when they are added to water, they will break down and become evenly distributed throughout the water, forming a solution. This is in contrast to substances that do not mix with water, which will remain separate and not dissolve when added to water. The correct answer, "A substance which mixes with water," accurately describes soluble objects.

The correct answer is Salt, Sugar, Coffee. These substances are soluble in water, meaning they can dissolve in water to form a homogeneous mixture. When salt, sugar, or coffee is added to water, they will dissolve and become evenly distributed throughout the water, creating a solution.

After giving 14 mangoes to the poor children, Roopa will have 31 mangoes left with her.

The phrase "practice makes perfect" is a common saying that implies that the more one practices something, the better they will become at it. This phrase emphasizes the importance of consistent effort and dedication in order to achieve excellence or perfection in any skill or endeavor. The repetition of the word "perfect" in the answer reinforces the idea that continuous practice leads to improvement and ultimately to perfection.

The correct answer is Wood, Metal, Oil. Wood and metal are insoluble objects because they do not dissolve in water or other solvents. Oil is also insoluble as it does not mix with water.

The correct answer is "night". The word "night" is repeated three times, but only the first occurrence is capitalized. This suggests that the word "night" is the correct answer, regardless of the capitalization. The repetition of the word emphasizes that the moon only appears in the night sky.

Insoluble substances are those that do not mix with water. They cannot dissolve or form a homogeneous mixture with water. This is because the molecules of the substance do not have the necessary polarity or attractive forces to interact with the water molecules. Instead, insoluble substances tend to form separate phases or precipitates when mixed with water.

Stars are indeed bigger than the sun. While the sun is considered a medium-sized star, there are many stars in the universe that are much larger. The size of a star depends on its mass, and there are stars known as red giants and supergiants that can be hundreds or even thousands of times larger than the sun. Therefore, the statement "Stars are bigger than the sun" is true.

The given numbers are arranged in descending order. Starting from the smallest number, we have 11, followed by 25, then 58, and finally 60. This means that the numbers are listed from highest to lowest, with 60 being the largest number and 11 being the smallest number.

The given numbers are arranged in ascending order from the smallest to the largest. Starting with the smallest number, which is 10, the numbers are arranged in increasing order, with each subsequent number being greater than the previous one. Therefore, the correct answer is 10, 21, 52, 90.
