JMI 6th Entrance Paper 2019 answer key and explanation

31. Of the following cases, construction of which A is not possible?

  • (A) 7cm, 7cm, 13cm
  • (B) 10cm, 10cm, 20cm
  • (C) 5cm, 12cm, 14cm
  • (D) 3cm, 6cm, 7cm

Answer:

(B) 10cm, 10cm, 20cm

Explanation:

The triangle inequality theorem states that the sum of the lengths of any two sides of a triangle must be greater than the third side. In this case, 10 + 10 = 20, which is not greater than the third side (20), so this triangle cannot be constructed.


32. The needle of a needle clock at 3.10 form

  • (A) An acute angle

Explanation:

At 3:10, the minute hand is at the ‘2’ and the hour hand is slightly past the ‘3’. The angle formed between them is less than 90 degrees, making it an acute angle.

  • (A) Any part of the radius
  • (B) Any part of the diameter
  • (C) Any part of cord
  • (D) Any part of the circumference

34. Two angles are called adjacent angles if

  • (A) They have the same vertex
  • (B) They have equal measures
  • (C) They lie in two separate figures
  • (D) They have different vertices

Answer:

(A) They have the same vertex

Explanation:

35. The diameter of a circle whose radius is 7cm, is

  • (A) 21cm
  • (B) 44cm
  • (C) 3.5cm

Answer:

(D) 14cm

Explanation:

The diameter of a circle is twice its radius (d = 2r). Therefore, the diameter is 2 × 7 cm = 14 cm.
