Question

find the mode and median of n observations are 1400 and 1500 respectively find it's mean

Answer 1

Hi ,

mode = 1400 ,

Median = 1500 ,

We know that ,

Mode = 3median - 2 mean

1400 = 3 × 1500 - 2 mean

2 mean = 4500 - 1400

= 3100

Mean = 3100/2

= 1550

I hope this helps you.

Answer 2

Heya........!!!!

By using the relationship between mean , median and mode i.e

=>> Mode = 3median - 2mean

Given :

=> Mode = 1400
=> Median = 1500
=> Mean = ?

Substituting this in Relationship ,, we get :-

➡1400 = 3×1500 - 2mean

➡ 2 mean = 4500 - 1400

➡ 2mean = 3100

➡ Mean = 3100/2

➡➡ Mean =>> 1550 .

Hope It Helps You ^_^
