Each interior angle of a regular polygon is 140°. How many sides does the polygon have?
सही उत्तर: क) 9
Each exterior angle = 180° − 140° = 40°, and the number of sides = 360°/40° = 9.

The corresponding sides of two similar triangles are in the ratio 3 : 5. What is the ratio of their areas?
सही उत्तर: ग) 9 : 25
The areas of similar triangles are in the ratio of the squares of corresponding sides: 3² : 5² = 9 : 25.

The hypotenuse of a right-angled triangle is 26 cm. What is the radius of its circumcircle?
सही उत्तर: ख) 13 cm
In a right triangle the hypotenuse is a diameter of the circumcircle, so the radius is 26/2 = 13 cm.

What is the radius of the circle inscribed in a triangle whose sides are 6 cm, 8 cm and 10 cm?
सही उत्तर: क) 2 cm
It is a right triangle with area = 1/2 × 6 × 8 = 24 and semi-perimeter s = 12; inradius r = area/s = 24/12 = 2 cm.

What is the length of the longest rod that can be placed inside a box measuring 12 cm × 4 cm × 3 cm?
सही उत्तर: घ) 13 cm
The longest rod lies along the space diagonal: √(12² + 4² + 3²) = √(144 + 16 + 9) = √169 = 13 cm.

A wheel of radius 35 cm rolls along the ground. How many complete revolutions will it make in covering 1.1 km? (Take π = 22/7)
सही उत्तर: क) 500
Circumference = 2 × 22/7 × 35 = 220 cm. Distance = 1.1 km = 1,10,000 cm, so revolutions = 110000/220 = 500.

A speaks the truth in 60% of cases and B in 70% of cases. In what percentage of cases are they likely to contradict each other when stating the same fact?
सही उत्तर: घ) 46%
They contradict when one is truthful and the other is not: 0.6 × 0.3 + 0.4 × 0.7 = 0.18 + 0.28 = 0.46, i.e. 46%.

A letter is chosen at random from the word 'ASSASSINATION'. What is the probability that it is a vowel?
सही उत्तर: क) 6/13
The word has 13 letters, of which the vowels are A (3), I (2) and O (1) = 6, so P = 6/13.

A die is thrown twice. What is the probability of getting at least one six?
सही उत्तर: ख) 11/36
P(no six in either throw) = 5/6 × 5/6 = 25/36, so P(at least one six) = 1 − 25/36 = 11/36.
