Answer 1

Hello friend

Here is your answer !!!!!!!!!!!!!

===> Answer

Given :

Median = 156

Mode = 180

We have to find Mean = ?

We know that,

Mean - Mode = 3(Mean - Median)

By putting the given values we get,

Mean - 180 = 3 ( Mean - 156)

Mean - 180 = 3Mean - 468

468 - 180 = 2Mean

Mean = 288/2


Mean = 144


Therefore, the Mean = 144
