iii.Average of the first 25 natural numbers

iv.Average of the cubes of the first 5 natural numbers

List II

b.45

c.38.5

d.15

Ai-c, ii-d, iii-a, iv-b ✓ Correct

Bi-a, ii-b, iii-c, iv-d

Ci-b, ii-c, iii-d, iv-a

Di-d, ii-a, iii-b, iv-c

Correct answer: (A) i-c, ii-d, iii-a, iv-b

Explanation

The correct matching is i-c, ii-d, iii-a, iv-b.

Average of squares of the first 10 numbers = 385 / 10 = 38.5.

Average of the first 5 multiples of 5 = 75 / 5 = 15.

Average of the first 25 natural numbers = (25 + 1) / 2 = 13.

Average of cubes of the first 5 numbers = 225 / 5 = 45.
