Of 100 students, 50 study French, 40 study German and 30 study Spanish; 15 study French and German, 10 study German and Spanish, 12 study French and Spanish, and 5 study all three. How many study none of these languages?
सही उत्तर: ग) 12
n(F ∪ G ∪ S) = 50 + 40 + 30 − 15 − 10 − 12 + 5 = 88, so 100 − 88 = 12 study none.

What is the centroid of the triangle with vertices (1, 2), (3, 4) and (5, 0)?
सही उत्तर: क) (3, 2)
Centroid = ((1 + 3 + 5)/3, (2 + 4 + 0)/3) = (3, 2).

What is the slope of a line perpendicular to the line 3x − 4y + 5 = 0?
सही उत्तर: क) −4/3
The given line has slope 3/4. Perpendicular slopes multiply to −1, so the required slope is −4/3.

What are the coordinates of the point that divides the line segment joining (2, 3) and (8, 9) internally in the ratio 1 : 2?
सही उत्तर: ग) (4, 5)
By the section formula: x = (1 × 8 + 2 × 2)/3 = 4 and y = (1 × 9 + 2 × 3)/3 = 5.

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.
