7. Write the relationship connecting three measures of central tendency. Hence find mode when mean is 146 and median is 130 .

The Relation between mean,median and mode is 

3 median -2 mean =mode

mean =146

median =130

applying the formulae we get

3(130)-2(146)=mode

390-292=mode

98=mode


therefore mode is 98.
