.The substance which does not allow to pass heat are called..
- A.
Conductor
- B.
Good conductor
- C.
Insulator
- D.
Non conductor
Correct Answer
C. InsulatorExplanation
Insulators are substances that do not allow heat to pass through them easily. They have high resistance to heat transfer, which means they are poor conductors of heat. Unlike conductors, which readily allow heat to flow through them, insulators restrict the transfer of heat and keep it trapped within their structure. This property makes insulators useful in applications where heat insulation is required, such as in the construction of buildings or the manufacturing of insulating materials for electrical appliances.Rate this question:

- D.
Opaque
Correct Answer
D. OpaqueExplanation
Opaque substances do not allow light to pass through them. Unlike transparent or translucent materials, opaque substances block the transmission of light, making them appear dark or solid. This characteristic is due to the way the atoms and molecules are arranged in these substances, causing them to absorb or reflect light rather than allowing it to pass through.Rate this question:

The physical quantity which has both magnitude & direction is called?
- A.
Scalar quantity
- B.
Vector quantity
- C.
Both
- D.
None
Correct Answer
B. Vector quantityExplanation
A vector quantity is a physical quantity that has both magnitude and direction. This means that in order to fully describe a vector quantity, we need to specify not only how much of it there is (magnitude), but also the direction in which it acts. Examples of vector quantities include velocity, force, and displacement. Scalar quantities, on the other hand, only have magnitude and no direction. Examples of scalar quantities include temperature, mass, and time.Rate this question:

A group of students volunteered to finish a construction work in 25 days. 1Q of the students did not come and the work could be finished in 35 days. The original number of students in the group was.
- A.
25.00
- B.
37.00
- C.
28.00
- D.
35.00
Correct Answer
D. 35.00Explanation
Let's assume that the original number of students in the group is x. According to the given information, if all the students had come, the work would have been finished in 25 days. This means that the rate of work done by the students is 1/25.
However, 1/4 (1Q) of the students did not come. So, the number of students who came is 3/4 of the original number, which is (3/4)x. Now, the work could be finished in 35 days, which means that the rate of work done by the students is 1/35.
Using the concept of work done = rate × time, we can set up the equation:
(1/25) * x = (1/35) * (3/4) * x
Simplifying this equation, we find that x = 35. Therefore, the original number of students in the group was 35.00.Rate this question:

Primary school had an enrollment of 850 pupils in January 1970. In January 1980 the enrollment was 1,120; What was the percentage increase for the enrollment?
- A.
27.45
- B.
31.76
- C.
38.13
- D.
45.26
Correct Answer
B. 31.76Explanation
The percentage increase in enrollment can be calculated by finding the difference between the final enrollment (1,120) and the initial enrollment (850), dividing that difference by the initial enrollment, and then multiplying by 100. In this case, the calculation would be: (1,120 - 850) / 850 * 100 = 270 / 850 * 100 = 31.76%. Therefore, the correct answer is 31.76.Rate this question:

) The number, whose 7% is 42, is
- A.
200
- B.
300
- C.
600
- D.
400
Correct Answer
B. 300Explanation
To find the number, we can set up a proportion. Let x be the number we are trying to find. We know that 7% of x is equal to 42. So, we can write the proportion as 7/100 = 42/x. Cross-multiplying, we get 7x = 4200. Dividing both sides by 7, we find that x = 600. Therefore, the number is 600.Rate this question:

- A.
28
- B.

- C.
48
- D.
22
Correct Answer
C. 48Explanation
The given sequence alternates between adding 2 and adding 3 to the previous number. Starting with 5, we add 2 to get 7, then add 3 to get 10, and so on. However, after reaching 26, the pattern changes and the sequence starts adding 10 instead of 3. Therefore, the next number in the sequence would be 26 + 10 = 36. However, this number is not among the options provided. Therefore, the correct answer cannot be determined based on the given options.Rate this question:

. A’s mother is twice as old as A’s brother. A is 6 years yqunger than his brother but 4 years older than his sister. If A’s sister is 15 his mother’s age is: 50
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Based on the given information, we can determine that A's sister is 15 years old, and A is 4 years older than his sister, making A 19 years old. We also know that A is 6 years younger than his brother, so his brother must be 25 years old. Since A's mother is twice as old as A's brother, her age would be 2 times 25, which equals 50 years old. Therefore, the statement "If A's sister is 15, his mother's age is 50" is true.Rate this question:

. Mr. Rehraan ordered a car worth Rs.600.000 and was given a discount.Given that he paid Rs.57,0000 for his new car, calculate the percentage discount he received:
- A.
5%
- B.
7%
- C.
9%
- D.
10%
Correct Answer
A. 5%Explanation
Mr. Rehraan received a 5% discount on his car purchase. This means that he paid 95% of the original price. To calculate the discount percentage, we can set up the equation 95% of the original price is equal to Rs.570,000. By dividing Rs.570,000 by 95% and multiplying by 100, we can find that the original price of the car was Rs.600,000. Therefore, the discount percentage is 5%.Rate this question:

Correct Answer
B. ScannerExplanation
A scanner is a light sensitive device that converts drawings, printed text, or other images into digital form. It uses a combination of sensors and optics to capture the image and convert it into a digital file that can be stored, edited, or printed. Unlike a keyboard or printer, a scanner is specifically designed for image capture and does not have the capability to input or output text or images directly. OMR (Optical Mark Recognition) is a different technology used for reading and interpreting marked fields on forms, such as multiple-choice answer sheets.Rate this question:
