If n is the median and m is the mode of the following set of numbers, 2.4, 2.1, 1.6, 2.6, 2.6, 3.7, 2.1, 2.6, then (n, m) is
(2.6, 2.6)
(2.5, 2.6)
(2.6, 2.5)
(2.5, 2.1)
Correct answer is B
Arrange the numbers in order, 1.6, 2.1, 2.1| 2.4, 2.6| 2.6, 2.6, 3.7
n = median = 2.4+2.62
= 2.5
m = mode = 2.6
∴ (n, m) = (2.5, 2.6)
