Question

The median and mode of a frequency distribution are 8 and 10 respec-tively. The mean of the distribution will be
(a) 12cm (b)8cm(c)10cm(d)6cm​

Answer 1

Answer:

(D) 6cm.

Step-by-step explanation:

By Empirical Formula,

3median = 2mean + mode

Therefore by substituting the values,

3(8) = 2mean + 10

24 - 10 = 2mean

Therefore, mean = 12/2 = 6 cm.
