Question

If A and M be the arithmetic mean and median of first ten natural numbers, then relation between them will be –

(a) A > M

(b) A < M

(c) A = 1\over \text{M}

(d) A = M

WBBSE Class X Mathematics Statistics 01 Mark 2024

Answer

(d) A = M

Explanation:

10 Natural Number = 1, 2, 3, 4, …, 10

Sum of 10 natural number (∑x) = 1 + 2 + 3 + 4 + … + 10 = 55

Mean = \text{∑x}\over \text{n} = \text{55}\over \text{10} = 5.5

Median = 5 + 6\over 2[\katex] = 5.5
