  1. 3: 4
  2. 4: 3
  3. 9: 16
  4. 3: 4

Answers:

  1. Answer: (d)

Sum of the digits at odd places = 5 + 6 + 9 + 6 = 26 Sum of digits at even places = 4 + 7 + 7 + 8 = 26 Difference between the two values = 26 – 26 = 0 So, the given number is completely divisible by 11.

  1. Answer: (c)

After analysing the figure, we get P = 20 km

B = (7.5 + 7.5) = 15 km

H =?

According to the Pythagoras theorem, H2 = B2+ P2

H2 = (15)2 + (20)2

H2 = 225 + 400

H = √625 H = 25 Thus, the distance between starting point and end point is 25 km.

  1. Answer: (a)

  1. Answer: (d)

Let the three consecutive numbers be x, x + 1 and x + 2. According to the question, x + x + 1 + x + 2 = 1383 On solving, we get three numbers = 460, 461 and 462

  1. Answer: (d)

The adjacent angle are (2x) and (7x) as shown below.

Since these angles are supplementary, (2x) + (7x) = 180 (x) = 20

So, the angles are 40, 140, 40 and 140.

  1. Answer: (b)

Sum of supplementary angles is 180. Therefore, (4x) + (5x) = 180 (x) = 20 So, the angles are 80 and 100.

  1. Answer: (c)
  2. Answer: (d)

Let the original number of oranges be x.

Oranges left = 30% of x = 360

x= 100/30×360=1200

Original number of oranges = 1200

  1. Answer: (c)

Let the number be x.

31% of x – 13% of x = 576

18% of x = 576

1% of x = 576/18 = 32

17% of x = 17 × 32 = 544

  1. Answer: (b)

Let the radius be r and height of the cylinder is h. Now,
