A distribution has mean 40 and standard deviation 10. What is its coefficient of variation?
सही उत्तर: ग) 25%
Coefficient of variation = (SD/mean) × 100 = 10/40 × 100 = 25%.

-
If 5 is added to every observation in a data set, what happens to its standard deviation?
सही उत्तर: घ) It remains unchanged
Standard deviation measures spread about the mean; adding a constant shifts every value and the mean equally, so the SD does not change.

What is the standard deviation of the observations 2, 4, 6, 8 and 10 (population formula)?
सही उत्तर: क) 2√2
Mean = 6; squared deviations are 16, 4, 0, 4, 16 with total 40. Variance = 40/5 = 8, so SD = √8 = 2√2.

What is the volume of a cone of base radius 3 cm and height 7 cm? (Take π = 22/7)
सही उत्तर: ख) 66 cu cm
V = 1/3 πr²h = 1/3 × 22/7 × 9 × 7 = 66 cubic cm.

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.

-
A solid metal sphere of radius 3 cm is melted and recast into small spheres, each of radius 1 cm. How many small spheres are obtained?
सही उत्तर: ख) 27
Volumes are proportional to the cube of the radius: (3/1)³ = 27 small spheres.

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.
