The average speed of a bus is three-fifth the average speed of a car which covers 3250 kms. in 65 hours. What is the average speed of the bus
- A.
30 kmph
- B.
20 kmph
- C.
35 kmph
- D.
36 kmph
- E.
None of these
Correct Answer
A. 30 kmpHExplanation
The average speed of the car can be calculated by dividing the total distance covered (3250 km) by the total time taken (65 hours), which gives us 50 kmph. Since the average speed of the bus is three-fifths of the car's average speed, we can calculate it by multiplying the car's average speed by three-fifths. Therefore, the average speed of the bus is (3/5) * 50 kmph, which equals 30 kmph.Rate this question:

If a number is added to two-fifth of itself, the value so obtained is 455. What is the number?
- A.
400
- B.
350
- C.
325
- D.
420
- E.
None of these
Correct Answer
C. 325Explanation
The question states that if a number is added to two-fifth of itself, the result is 455. To find the number, we can set up an equation. Let's assume the number is x. Two-fifth of x is (2/5)x. Adding x to (2/5)x gives us the equation x + (2/5)x = 455. Simplifying this equation, we get (7/5)x = 455. To solve for x, we can multiply both sides of the equation by 5/7. This gives us x = (455 * 5)/7 = 325. Therefore, the number is 325.Rate this question:

The body weight of seven students of a class is recorded as 54 kg., 78 kg., 43 kg., 82 kg., 67 kg., 42 kg., and 75 kg., What is the average body weight of all the seven students?
- A.
69 kg.
- B.
63 kg.
- C.
71 kg.
- D.
73 kg.
- E.
None of these
Correct Answer
B. 63 kg.Explanation
The average body weight of all the seven students can be calculated by adding up the individual weights of the students and then dividing the sum by the total number of students. In this case, the sum of the weights is 54 + 78 + 43 + 82 + 67 + 42 + 75 = 441 kg. Since there are seven students, the average body weight would be 441 kg divided by 7, which equals 63 kg.Rate this question:

- C.
Rs. 58,500
- D.
Rs. 28,230
- E.
None of these
Correct Answer
C. Rs. 58,500Explanation
The question states that Sukhwinder's annual income is Rs. 2.34 lacs. To find Ganeshi's monthly income, we need to first find Jassi's monthly income. It is given that two-thirds of Jassi's monthly income is equal to Sukhwinder's monthly income. So, Jassi's monthly income can be calculated by dividing Sukhwinder's annual income by 12 and then multiplying it by 2/3. Once we have Jassi's monthly income, we can find Ganeshi's monthly income by multiplying it by 2. Therefore, the correct answer is Rs. 58,500.Rate this question:

The angles of a triangle are in ratio of 3 : 5 : 4 respectively. What is the difference between twice the smallest angle and the second largest angle of the triangle?
- A.
25°
- B.
10°
- C.
45°
- D.
30°
- E.
None of these
Correct Answer
D. 30°Explanation
The angles of a triangle are in the ratio of 3:5:4. Let's assume the smallest angle is 3x, the second largest angle is 5x, and the largest angle is 4x. The sum of the angles of a triangle is 180°, so we can set up the equation 3x + 5x + 4x = 180°. Solving this equation, we find that x = 12°. Therefore, the smallest angle is 3(12°) = 36° and the second largest angle is 5(12°) = 60°. Twice the smallest angle is 2(36°) = 72°. The difference between 72° and 60° is 72° - 60° = 12°. However, the question asks for the difference between twice the smallest angle and the second largest angle, so the correct answer is 72° - 60° = 30°.Rate this question:

One of the angle of a parallelogram is . What is the sum of half the smallest angle and twice the largest angle of the parallelogram?
- A.
256°
- B.
307°
- C.
297°
- D.
Cannot be determined
- E.
None of these
Correct Answer
C. 297°Explanation
The sum of half the smallest angle and twice the largest angle of a parallelogram can be found by using the properties of a parallelogram. In a parallelogram, opposite angles are equal. Since one angle of the parallelogram is given as 256°, the opposite angle will also be 256°. Therefore, the smallest angle of the parallelogram is 256°. The largest angle of the parallelogram will be the opposite angle, which is also 256°. Hence, half the smallest angle is 128° and twice the largest angle is 512°. The sum of these two angles is 128° + 512° = 640°. However, none of the given answer choices match this sum. Therefore, the correct answer cannot be determined.Rate this question:

In how many different ways can the letters of word 'REMAKE' be arranged?
- A.
720
- B.
60
- C.
360
- D.
180
- E.
None of these
Correct Answer
C. 360Explanation
The word "REMAKE" has 6 letters. To find the number of different ways these letters can be arranged, we use the formula for permutations of n objects taken all at a time, which is n!. In this case, 6! = 6 x 5 x 4 x 3 x 2 x 1 = 720. However, since the letter "E" appears twice, we must divide by the factorial of the number of times it repeats, which is 2!. Therefore, the total number of different ways the letters of the word "REMAKE" can be arranged is 720 / 2! = 360.Rate this question:

- D.
18 cm.
- E.
None of these
Correct Answer
B. 21 cm.Explanation
The perimeter of a square is equal to 4 times its side length. The perimeter of the rectangle is equal to 2 times its length plus 2 times its width. Given that the perimeter of the square is equal to the perimeter of the rectangle, we can set up the equation 4s = 2(30) + 2w, where s is the side length of the square and w is the width of the rectangle. Since the area of the rectangle is 360 sq. cm, we can also set up the equation lw = 360. Solving these two equations simultaneously, we find that the side length of the square is 21 cm.Rate this question:
