Question

The median and mode of a frequency distribution of height of 1000 students are 139.69 cms and 140.05 cms respectively. The mean height of students is ?

Answer 1

Step-by-step explanation:

mode=3 median-2mean

140.05=3(139.69)- 2 mean

140.05=419.07-2mean

2mean = 410.07-140.05

2mean=279.02

mean =279.02/2

mean=139.51

MEAN=139.51
